It seems to me very this kind of the trick I mentioned, namely via
that small F77_NAME macro we define
#define ffread_ F77_NAME(ffread,FFREAD)
This macro for the different platforms does supply:
1. ffread_ as ffread_
2. ffread_ as ffread
3. ffread_ as FFREAD
but within your source you are still using your "more readable
and robust" form, namely
ffread_( . . . )
Actually at this place you have no deal with any compiler just with
C/C++ pre-processing only.
