It may seem weird, but I don't see a way to support -mcygwin on Cygwin :)

winecrt0 is linked to both modules converted to PE files and not converted
ones. On PE targets, it means that those debug functions get linked to all
modules. They need to get stderr, which depends on crt used. In -mcygwin case
we should use Cygwin libc, but it was earlier built with msvcrt definitions. We
get away with it on mingw because mingw crt is compatible with msvcrt in this
case.

I don't see an easy way around it, you may disable problematic modules with
configure options for now. The problem will not exist once we convert remaining
modules to PE files.
