No, you're right, there will always be _an_ f2c.h found; the question
is whether it's consistent with (a) the libf2c.a that gets linked (b)
been compiled into g77 regarding type sizes.

It's particularly useful as an interface generator if you're mixing
Fortran and C or something else via a SWIG-like scheme.  [`f2c -P'
gives you C prototypes for the fortran routines corresponding to the
g77 default code generation.]  Presumably G77 could do this, but it
doesn't currently.  It may end up translating more for the g77 runtime
at some stage, but that's not necessarily a reason for distributing it
with g77, and I suspect the things it does that g77 doesn't aren't now
compelling.
