gnu/packages/patches/gcc-boot-4.6.4.patch

   1 This patch enables building gcc-4.6.4 using gcc-2.95.3 and glibc-2.2.5
   2
   3   * Tweak Makefile to allow overriding NATIVE_SYSTEM_HEADER_DIR using #:makeflags
   4   * Add missing limits.h include.
   5   * Add SSIZE_MAX define.  The SSIZE_MAX define has been added to Mes
   6     upstream and can be removed with the next Mes release.
   7   * Remove -fbuilding-libgcc flag, it assumes features being present from a
   8     newer gcc or glibc.
   9   * [MES_BOOTSTRAP_GCC]: Disable threads harder.
