Wrt gnu compilers last I checked - fortran common blocks [requiring
dllexport stuff] was and issue. [perhaps gfortran doesn't have proper
support for it yet - don't know]

The other issue to fix would be gmakefile compile command. [currently
gcc/dll works with cmake build using --with-fc=0]

Wrt MS compilers - I haven't checked. [last I checked - I got bogged
down with cmake stuff - and didn't get a working dll]

The 'fortran commom block' stuff probably works with ifort [with the
required preprocessor directives]. Presumably txcorp and mic-tc have
patches for that.  The other issue is the build command to get dlls
with MS compilers [via gmakefile]. I think txcorp uses cmake and
presumably mic-tc uses MS project files..
