#280 mingw cross-compilation fails with gcc8.1.0

[CitrusLevi]

I tried to cross compile with the latest gcc release and mingw commit bcf1f29d6dc80b6025b416bef104d2314fa9be57 from master and receive this error:

libtool: link: x86_64-w64-mingw32-gcc -O2 -o timepng.exe contrib/libtests/timepng.o  ./.libs/libpng16.a -lz

make[1]: *** [Makefile:1159: contrib/libtests/pngvalid.o] Error 1
make[1]: Leaving directory 'libpng_git'
make: *** [Makefile:792: all] Error 2

Any idea what causes this?

I am running into this same error. Did you ever resolve this?
