I assume that FC and CC are for use by make, so I put them in a
makefile and tried a test program with the following result:

cdr@dell03 ~/mingtest
$ make hello
i686-w64-mingw32-gfortran.exe    hello.f   -o hello

cdr@dell03 ~/mingtest
$ ./hello
/home/cdr/mingtest/hello.exe: error while loading shared libraries: 
libgfortran-
3.dll: cannot open shared object file: No such file or directory
