This also occurs on Fedora right now. AFAICS, the culprit is that the latest Cygwin w32api package doesn't match the files from mingw-crt for some reason. The build uses -L/usr/lib/w32api (-L/usr/i686-pc-cygwin/lib/w32api when cross building on Fedora), so the libs are taken from the w32api-runtime package. However, the compiler uses the default crt file /usr/i686-w64-mingw32/sys-root/mingw/lib/../lib/crt2.o which is provided by the mingw-crt package. This is a bug in Cygwin's Makefile since you should never use the w32api stuff for mingw executables, only for Cygwin executables, but still... JonY, do you have an idea why the mingw-crt differs that much from the w32api stuff that the above error occurs?
