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.
