I think these testsuite problems goes away if you configure with something like ".../configure --build=i686-pc-cygwin --host=mingw32" as indicated in the manual [1]. Or maybe it's x86_64-pc-cygwin in your case? The rationale is that when Cygwin is used to drive a MSVC build, I have considered it a Cygwin to MinGW cross, because that is much closer to the truth than a native Cygwin build (which is what is assumed if you just override CC). But I haven't tested recently, YMMV... Cheers, Peter [1] https://www.gnu.org/software/libtool/manual/libtool.html#Cygwin-to-MinGW-Cross
