## compiler. On some Cray systems, fort77 is a native compiler.
## cf77 and cft77 are (older) Cray F77 compilers.

## What we really should do is determine how to properly mangle the
## names of C/C++ identifiers (potentially containing underscores) so
## that they match the name-mangling scheme used by the Fortran 77
## compiler. Autoconf 2.50 or better has macros F77_FUNC(name, NAME)
## and F77_FUNC_(name, NAME) for this. However, the F77_* macros in
## the R API have one argument only and therefore cannot deal with
## Fortran 77 compilers which convert to upper case or add an extra
## underscore for identifiers containing underscores. We give an error
## in the former case; as ISO Fortran 77 does not allow underscores in
## function names, we do nothing about the latter.
