>Description:

Compiling a .F source (thus requesting preprocessing) with the
-ffixed-line-length-132 option gives a bogus warning:

$ touch x.F
$ g77 -c -ffixed-line-length-132 x.F
cc1: warning: unknown register name: line-length-132
$

It looks like the fortran option is getting passed to the cc1 invocation
used for preprocessing:
