No, MinGW-w64 doesn't depend on Cygwin. http://openfoamwiki.net/index.php/Tip_Cross_Compiling_OpenFOAM_in_Linux_For_Windows_with_MinGW#Differences_between_mingw32_and_mingw-w32_versions
Mingw-w64 began as a spin-off from the mingw.org project, with the original intent of building for 64-bit targets. Nonetheless, mingw-w64 has retro-compatibility with the 32bit MinGW version, thus enabling a 2-in-1 build package for 32 and 64bit Windows systems.
