on mingw32: make check shows 1265 test failures

[glycerine]

rust version:

• master 7820fb5 auto merge of Remove and cleanup functions in std::vec #9062 : blake2-ppc/rust/vec-iterator, r=alexcrichton

1. win32 install: following https://github.com/mozilla/rust/wiki/Note-getting-started-developing-Rust for Windows 8
2. installed mingw (32-bit), and prereqs.
3. installed ftp://sourceware.org/pub/pthreads-win32/pthreads-w32-2-9-1-release.zip, as per updated https://github.com/mozilla/rust/wiki/Note-getting-started-developing-Rust when I ran into 'libpthreadGC2.dll not found problem'.
4. make builds rust, but make check fails 1265 tests. Transcript below.

Am I not building right... maybe the pthreadGC2.dll was not compatible after all? Just reaching at straws here.

On win32 we only check make check-fast only. I've heard before that make check is broken on win32, but don't know current status.

This is fixed: #10452

hurray, thanks!
