gfortran currently supports only STDCALL, FASTCALL and CDECL as attributes using
!GCC$ ATTRIBUTE <list> :: symbol The attributes are saved as bit in the attr struct. For full attribute support, one presumably should save the string and convert it later in trans*.c into a TREE. The string should then be saved in the .mod file. (That is also the reason that one cannot directly save the attributes into a TREE.) Issue: For STDCALL etc. we do some conformance checking for proc-pointer assignments. That should continue to work. Maybe one needs to do further checks.
