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

22 Subject: Patches to build gcc 3.4.3 / glibc 2.3.5 on cygwin
25 following patches are needed to build gcc-3.4.3/glibc-2.3.5 toolchain
26 on cygwin. Tested to build toolchains for powerpc 604 and 750 targets.
