dnl *********************************
dnl
dnl PAC_FC_SEARCH_LIST - expands to a whitespace separated list of modern
dnl fortran compilers for use with AC_PROG_FC that is more suitable for HPC
dnl software packages
AC_DEFUN([PAC_FC_SEARCH_LIST],

dnl
dnl PAC_PROG_FC([COMPILERS])
dnl
dnl COMPILERS is a space separated list of Fortran compilers to search for.
dnl
dnl Compilers are ordered by
dnl 1. F90, F95, F2003
dnl 2. Good/tested native compilers, bad/untested native compilers
dnl 3. Wrappers around f2c go last.
dnl
dnl frt is the Fujitsu Fortran compiler.
dnl pgf90 are the Portland Group F90 compilers.
dnl xlf/xlf90/xlf95/xlf2003 are IBM (AIX) F90/F95/F2003 compilers.
dnl lf95 is the Lahey-Fujitsu compiler.
dnl fl32 is the Microsoft Fortran "PowerStation" compiler.
dnl epcf90 is the "Edinburgh Portable Compiler" F90.
dnl fort is the Compaq Fortran 90 (now 95) compiler for Tru64 and Linux/Alpha.
dnl pathf90 is the Pathscale Fortran 90 compiler
dnl ifort is another name for the Intel f90 compiler
dnl efc - An older Intel compiler (?)
dnl ifc - An older Intel compiler
dnl fc - A compiler on some unknown system. This has been removed because
dnl it may also be the name of a command for something other than
dnl the Fortran compiler (e.g., fc=file system check!)
dnl gfortran - The GNU Fortran compiler (not the same as g95)
dnl gfc - An alias for gfortran recommended in cygwin installations
dnl NOTE: this macro suffers from a basically intractable "expanded before it
dnl was required" problem when libtool is also used
dnl [1] MPICH.org
