That's because you're using -mno-cygwin.  That flag essentially turns
gcc into mingw, and none of the Cygwin libraries or headers are in the
search path for mingw.  They wouldn't work even if they were because
they all depend on cygwin1.dll.  A cygwin-ported library is of no use if
you're using mingw.
