'fc' program and autoconf

[Bob Friesenhahn]

Autoconf 2.53 (via autoconf.m4f) considers 'fc' to be a candidate when
searching for a FORTRAN compiler. Unfortunately, 'fc' conflicts with a
Korn-shell related program found under SVR4-derived systems, or other
systems providing the Korn shell:

DESCRIPTION
  /usr/bin/fc
     The fc utility lists or edits and reexecutes, commands  pre-
     viously entered to an interactive sh.

When the system does not have any other FORTRAN compiler installed,
configure selects 'fc' as the FORTRAN compiler:

F77 = fc

even when fc is actually the program from the Korn-shell.
