I suspect this is the same bug as I have been digging into. Using GCC 4.9.2 on
Cygwin the tests fail with errors like:
"Win32::API a function was called with the wrong prototype and caused a C stack
inconsistency EBP=28c9ec ESP=28c9e0 at t/00_API.t line 51."
Adding -fno-schedule-insns2 to the CFLAGS (see patch) fixes it for me
(-fno-schedule-insns2 seems to be supported at least as far back as GCC 3.3.3
so I assume this should not cause any issues for older installs).
