This patch enables building gcc-4.6.4 using gcc-2.95.3 and glibc-2.2.5 * Tweak Makefile to allow overriding NATIVE_SYSTEM_HEADER_DIR using #:makeflags * Add missing limits.h include. * Add SSIZE_MAX define. The SSIZE_MAX define has been added to Mes upstream and can be removed with the next Mes release. * Remove -fbuilding-libgcc flag, it assumes features being present from a newer gcc or glibc. * [MES_BOOTSTRAP_GCC]: Disable threads harder. Upstream status: not presented upstream. diff --git a/gcc/Makefile.in b/gcc/Makefile.in index f3cc49fdb18..bc5718fc9a6 100644 --- a/gcc/Makefile.in +++ b/gcc/Makefile.in @@ -440,7 +440,7 @@ LINKER_PLUGIN_API_H = $(srcdir)/../include/plugin-api.h LTO_SYMTAB_H = $(srcdir)/../include/lto-symtab.h # Default native SYSTEM_HEADER_DIR, to be overridden by targets. -NATIVE_SYSTEM_HEADER_DIR = /usr/include +# NATIVE_SYSTEM_HEADER_DIR = /usr/include # Default cross SYSTEM_HEADER_DIR, to be overridden by targets.
