Actually, the OP hasn't really specified whether he is using the
*cygwin* provided mingw64 *cross compilers*, or if he has simply
installed the mingw64 *native* compilers from mingw-w64.sourceforge.net.

If the latter...well, why would you expect that a w64 native windows
compiler would ever be able to generate apps that use the cygwin
unix/posix services?

If the former...same thing, really.  The compiler generates NATIVE w64
code, and the generated code uses the W64 native windows runtime
services: NOT the cygwin runtime services.  The only real differences in
these two compilers is that the cygwin-hosted cross compiler can use
cygwin services during the BUILD process. But the generated executables
are, ideally, IDENTICAL to those created by a regular, normal, native
W64 compiler.

What it SEEMS the OP wants is a 64bit cygwin compiler.  There is no such
beast.  Sorry.
