vasilito facf0c92e0 feat: track all source trees in git — full fork offline-first model 
Red Bear OS is a full fork. All sources must be available from git clone
with zero network access. Removed gitignore rules that excluded fetched
source trees under recipes/*/source/, local/recipes/kde/*/source/,
local/recipes/qt/*/source/, and vendor source trees.

Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded.

127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt
frameworks, mesa, wayland, DRM drivers, and every other recipe source.

Suppress extern inline with HP-UX cc, as it appears to be broken; see
<https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
Suppress extern inline with Sun C in standards-conformance mode, as it
mishandles inline functions that call each other. E.g., for 'inline void f
(void) { } inline void g (void) { f (); }', c99 incorrectly complains
'reference to static identifier "f" in extern inline function'.
This bug was observed with Oracle Developer Studio 12.6
(Sun C 5.15 SunOS_sparc 2017/05/30).
Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
on configurations that mistakenly use 'static inline' to implement
functions or macros in standard C headers like <ctype.h>. For example,
if isdigit is mistakenly implemented via a static inline function,
a program containing an extern inline function that calls isdigit
may not work since the C standard prohibits extern inline functions
from calling static functions (ISO C 99 section 6.7.4.(3).
This bug is known to occur on:
OS X 10.8 and earlier; see:
https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
DragonFly; see
http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
FreeBSD; see:
https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
Assume DragonFly and FreeBSD will be similar.
GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
inline semantics, unless -fgnu89-inline is used. It defines a macro
__GNUC_STDC_INLINE__ to indicate this situation or a macro
__GNUC_GNU_INLINE__ to indicate the opposite situation.
GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
semantics but warns, unless -fgnu89-inline is used:
warning: C99 inline functions are not supported; using GNU89
warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

that is intended to inspect a variable set from within a signal handler
while (!signal_occurred)

dnl not require -lm, but taking the function pointer of 'fabs' does.
dnl 2) On MSVC 9, many math functions exist only as macros with arguments,

dnl exist as macros with arguments, that may reference libm or even

dnl rint() with simple arguments are turned into rintf() calls by the

/* alignof (TYPE), also known as _Alignof (TYPE), yields the alignment
requirement of a structure member (i.e., slot or field) that is of
type TYPE, as an integer constant expression.
This differs from GCC's and clang's __alignof__ operator, which can
yield a better-performing alignment for an object of that type. For
example, on x86 with GCC and on Linux/x86 with clang,
__alignof__ (double) and __alignof__ (long long) are 8, whereas
alignof (double) and alignof (long long) are 4 unless the option
'-malign-double' is used.
The result cannot be used as a value for an 'enum' constant, if you
want to be portable to HP-UX 10.20 cc and AIX 3.2.5 xlc. */

example:

A should be a power of two that is at least the type's alignment

2**28 on typical GNUish hosts, and 2**13 on MSVC. To be portable

constant, as MSVC does not support expressions such as 1 << 3.
To be portable to Sun C 5.11, do not align auto variables to
anything stricter than their default alignment.
The following C23 requirements are not supported here:
- If A is zero, alignas has no effect.
- alignas can be used multiple times; the strictest one wins.
- alignas (TYPE) is equivalent to alignas (alignof (TYPE)).

dnl First, the warnings that are generated already with -O0:
dnl These warnings enforce a certain programming style that is not ours.
nw="$nw -Wempty-body"

dnl All warnings produced by these options (in gcc 13) have been false
dnl alarms.
nw="$nw -Wanalyzer-double-fclose"

nw="$nw -Wanalyzer-fd-double-close"
nw="$nw -Wanalyzer-null-argument"
nw="$nw -Wanalyzer-null-dereference"
nw="$nw -Wanalyzer-use-of-uninitialized-value"
dnl This warning option is nonsense. It's normal to have to cast, for
dnl example, a 'double' to an 'int'. When that 'double' value is the
dnl result of a function call, this does not make the cast dangerous
dnl in any way.
nw="$nw -Wbad-function-cast"
dnl When we allocate memory for several objects through a single malloc()
dnl call, it's normal that we then have to cast a 'char *' to various
dnl pointer types with varying alignment.
nw="$nw -Wcast-align"
dnl We use computed format strings in a number of places, and glibc's
dnl <bits/error.h> does it as well.
nw="$nw -Wformat-nonliteral"
dnl We define a few functions for binary backward compatibility only.
dnl These functions are not declared on purpose: So that they cannot be
dnl accidentally used in new code.
nw="$nw -Wmissing-declarations"
nw="$nw -Wmissing-prototypes"
dnl We frequently have a static variable and a local variable in a function
dnl with the same name. This is normal, because the same concept often
dnl occurs in multiple locations in a file. Thus, ignore
dnl "... shadows a global declaration" warnings. Only
dnl "... shadows a parameter" and "... shadows a previous local" warnings
dnl are worth eliminating; see below.
nw="$nw -Wshadow"
dnl Too many warnings. We often use signed types like 'int' or 'idx_t'
dnl for counter variables, yet SIZEOF(array) is an unsigned value.
nw="$nw -Wsign-compare"
dnl This warning is based on older ISO C standards. It warns, in particular,
dnl about function definitions that are valid in ISO C 23 (static and
dnl non-static functions). Cf.

nw="$nw -Wstrict-prototypes"
dnl There is no reason to warn about an abstract (unimplemented) method in
dnl an abstract class; it has no chance of ever being called. Only the
dnl implementations of the method on concrete subclasses can be called.
nw="$nw -Wsuggest-attribute=noreturn"
dnl There is no reason to warn about code that does not want to make
dnl assumptions about whether a certain type is signed or unsigned.
nw="$nw -Wtype-limits"
dnl Too many warnings. #if preprocessor directives often lead to unused
dnl macros.

dnl Unused parameters are frequent in functions that are meant to implement
dnl a given function type.

dnl Some of these warnings point to functions for which the result's
dnl destruction should be done through fclose(), <datatype>_free(), etc.,
dnl not free().
