Thanks.  This is the culprit:

It's set correctly during the configure run at first, then later
overwritten wrongly in the FC bits.  Hmm, for some reason configure
thinks then that $FC isn't the GNU compiler, and puts in non-GCC bits. 

Anyway, there is some bogosity in the FC bits in libtool.m4, could you
please try a shared build with FC=no for your package?  That should be
a workaround until we have a proper fix.

Please note that I was not able to build your package under MinGW/MSYS:
it errored out with:

This is still obscure to me.  struct stat is defined in
MinGW/include/sys/stat.h, for the shared build something defines stat to
stat64, which isn't defined.  The static build completes and passes the
test suite. 

Cheers,
