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.
