gfortran, since 4.2, supports OpenMP parallel compilation (but

Yes it does support OpenMP on Windows, providing that a POSIX thread
library is available. As an example, the Windows binaries of gfortran
regularly built and available at http://gcc.gnu.org/wiki/GFortranBinaries
include OpenMP support (using the pthreads-win32 library, provided in the
installer).

In my installation of the 64-bit mingw binaries from the wiki, there is
no gomp specs file. In my experience of building gcc on windows, this
is a normal consequence of not enabling libgomp in the build.
Evidently, a pthreads-win64 library would be required here. OpenMP
support is not enabled in a default Windows build of gcc, although I do
always include it in my Cygwin builds.
