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.
