| Fixes |
| elf/librtld.os: In function `process_envvars': : undefined reference to `__access' |
| ... |
| when building glibc-2.3.x on cygwin |
| |
| Idea from |
| http://sources.redhat.com/ml/bug-glibc/2002-01/msg00071/glibc-2.2-cygin-shared.patch |
| Basically, make glibc use .oST as suffix for 'object static' |
| instead of .oS, since cygwin has trouble distinguishing .os from .oS |
| (Original patch had .on, but .oST is more mnemonic for 'object static') |
| |
| glibc-linuxthreads-2.3.5 also requires a patch, see |
| ../glibc-linuxthreads-2.3.5/glibc-linuxthreads-2.3.5-cygwin.patch |

| Subject: Patches to build gcc 3.4.3 / glibc 2.3.5 on cygwin |
| |
| Hi Dan, |
| following patches are needed to build gcc-3.4.3/glibc-2.3.5 toolchain |
| on cygwin. Tested to build toolchains for powerpc 604 and 750 targets. |
