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.

this header file "mpfr-intmax.h" is included in a consistent way,

different platforms and compilation options. Note that in particular,

it needs <limits.h> (always included first in "mpfr-impl.h") if

<inttypes.h> or <stdint.h> does not exist or does not work. It also

needs "config.h" if used (HAVE_CONFIG_H defined), but "config.h" is

also included first in "mpfr-impl.h". */
