yann@434: when building glibc-2.3.x on cygwin
yann@434: 
yann@434: Idea from
yann@434: http://sources.redhat.com/ml/bug-glibc/2002-01/msg00071/glibc-2.2-cygin-shared.patch
yann@434: Basically, make glibc use .oST as suffix for 'object static'
yann@434: instead of .oS, since cygwin has trouble distinguishing .os from .oS
yann@434: (Original patch had .on, but .oST is more mnemonic for 'object static')
yann@434: 
yann@434: glibc-linuxthreads-2.3.5 also requires a patch, see
yann@434: ../glibc-linuxthreads-2.3.5/glibc-linuxthreads-2.3.5-cygwin.patch

yann@434: 
yann@434: Hi Dan,
yann@434: following patches are needed to build gcc-3.4.3/glibc-2.3.5 toolchain
yann@434: on cygwin. Tested to build toolchains for powerpc 604 and 750 targets.
