           Summary: Update expr.c's check_inquiry for C_SIZEOF,
                    compiler_version/_options, etc.
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Keywords: rejects-valid

         Component: fortran

Follow up to PR 40568 - but also to PR 40569. The PR of the former - I might
not have copied all remaining tasks.


ISO_C_BINDING's C_SIZEOF but also ISO_FORTRAN_ENV's
compiler_options/compiler_version as listed under Fortran 2008's "7.1.11 Sp=
eci
cation expression" as "speci=0Ccation inquiry".

If I understood this part of the previous PR correctly, it means that expr.=
c's
check_inquiry needs to be updated.

I think except for some F95 vs. newer checks, most items should be handled =
via
flags in add_function/subroutine of intrinsic.c as one easily forgets to up=
date
check_inquiry.
