Assuming you installed it, probably gfortran (GNU Fortran).  Cygwin is not a monolithic
install like a Linux OS.  It is a library that maps POSIX library calls onto Windows
functionality as best it can.  This is often good enough to support recompiling a
Linux (POSIX compatible) program and getting it to run with essentially the same
functionality under Windows.

Mingw is different from Cygwin.  It aims the support building Windows-native
applications using the GNU compiler suite.  It targets Windows directly as opposed
Cygwin gcc, which targets the Cygwin library interface.

Anyway, maybe this Stack Overflow post will behelpful to you:
