Comment (by hinder):

 I agree.  If the user has specified a Fortran compiler in their optionlist
 and that compiler does not exist, this should be an immediate fatal error.
 It indicates either that the user has made an error in the optionlist,
 that the machine configuration has changed, or that the optionlist is not
 suitable for that system.  All of these should be caught as early as
 possible.

 The only argument I can see for this not being an error is if the user
 wants to use a "generic" optionlist for C thorns only on a system which
 doesn't have a Fortran compiler.  If we really want to support this case,
 then we need to ensure that the entire configuration stage works with an
 invalid Fortran compiler, and I think this is unnecessarily complicated.
 The user can easily work around that by either setting F90 = none on the
 command line, or editing the optionlist.
