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.

/* One of the goals of this test is to detect potential issues with the
|
|
* following case in user code:
|
|
*
|
|
* #include <some_lib.h>
|
|
* #include <stdint.h>
|
|
* #define MPFR_USE_INTMAX_T
|
|
* #include <mpfr.h>
|
|
*
|
|
* where some_lib.h has "#include <mpfr.h>". So, the mpfr.h header file
|
|
* is included multiple times, a first time without <stdint.h> before,
|
|
* and a second time with <stdint.h> support. We need to make sure that
|
|
* the second inclusion is not a no-op due to some #include guard. This
|
|
* was fixed in r7320.
|
|
*
|
|
* With mini-gmp, mpfr-impl.h is included first, but this should not
|
|
* affect this test.
|
|
*
|
|
* Note: If _MPFR_EXP_FORMAT == 4 (which is never the case by default),
|
|
* a part of the above check is not done because <stdint.h> is included
|
|
* before the first mpfr.h inclusion (see above).
|
|
*
|
|
* Moreover, assuming that this test is run on a platform that has
|
|
* <stdint.h> (most platforms do nowadays), without mini-gmp, this
|
|
* test also allows one to detect that mpfr.h can be included without
|
|
* any other inclusion before[*] (such as <stdio.h>). For instance,
|
|
* it can detect any unprotected use of FILE in the mpfr.h header
|
|
* file.
|
|
* [*] possibly except config.h when used, which is normally not the
|
|
* case with a normal build. Anyway, if we decided to change that,
|
|
* this inclusion would not change anything as config.h would only
|
|
* have defines (such as HAVE_STDINT_H) currently provided as "-D"
|
|
* compiler arguments.
