| 9a935f66 | 1 | This patch enables building gcc-4.6.4 using gcc-2.95.3 and glibc-2.2.5 |
| 0b652851 JN |
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. | |
