If this is the case, one could try:

!GCC$ ATTRIBUTES DLLIMPORT :: common_name

cf.
http://gcc.gnu.org/onlinedocs/gfortran/GNU-Fortran-Compiler-Directives.html

Note: This is a new GCC 4.5 feature (cf.
http://gcc.gnu.org/gcc-4.5/changes.html ). I stress this because
previous GCC Fortran versions simply ignore this line as comment. (I
think DLLIMPORT/DLLEXPORT has not yet been tested for COMMON blocks -
though it looks (from the gfortran source code) as if should work.)
