I'm seeing a couple of testsuite failures on MSYS: 'Input from stdin' and 'AC_CONFIG_FILES, HEADERS, LINKS, and COMMANDS'. Both fail due to issues with redirection of stdin.
It's interesting to note that running echo hello | ./micro-suite on the command line in the former test causes micro-suite to pass. Looks like a MSYS problem to me, I just haven't been able to narrow it down enough to report a bug with them. Cheers, Ralf
