## R_PROG_F77_OR_F2C
##
## Find a Fortran 77 compiler, or f2c.
##
## If we have not been forced to use a particular FORTRAN compiler, try
## to find one using one of the several common names.  The list is based
## on what the current autoconf CVS contains, and ordered by
##  1. F77, F90, F95
##  2. Good/tested native compilers, bad/untested native compilers
##  3. Wrappers around f2c go last.
##
## `fort77' and `fc' are wrappers around `f2c', `fort77' being better.
## It is believed that under HP-UX `fort77' is the name of the native
## compiler.  On some Cray systems, fort77 is a native compiler.
## cf77 and cft77 are (older) Cray F77 compilers.
## pgf77 and pgf90 are the Portland Group F77 and F90 compilers.
## xlf/xlf90/xlf95 are IBM (AIX) F77/F90/F95 compilers.
## lf95 is the Lahey-Fujitsu compiler.
## fl32 is the Microsoft Fortran "PowerStation" compiler.
## af77 is the Apogee F77 compiler for Intergraph hardware running CLIX.
## epcf90 is the "Edinburgh Portable Compiler" F90.
##
## The configure options `--with-g77', `--with-f77', or `--with-f2c'
## force g77, f77, or f2c to be used (under *exactly* these names).  It
## is also possible to use these options to specify the full path name
## of the compiler.
