Unquoting in _AC_PROG_FC_V_OUTPUT

[Ron McTaggart-Cowan]

Hi - I'm running into a problem with autoconf 2.59 Fortran macro 
_AC_PROG_FC_V_OUTPUT (used to be _AC_PROG_F77_V_OUTPUT) on a Linux Fedora system 
with Portland Group f90 compilers.  The Cray Fortran unquoting (removal of 
"-characters from the command line string at line 555 of fortran.m4) used to 
apply to all systems; it is now applied only for cft90 compilers - I'm wondering 
if the best way to proceed is to add the PGf90 compilers to this case selection, 
or to continue to remove quote characters from arguments in general?

Thanks,
ron
