[Bug fortran/35930] New: -pedantic: Check for -std=f95/f2003/f2008

I understood -pedantic such that it gives warnings if a construct does not
match the Fortran standard. Currently, it seems to be partially used such but
also used to warn for non-Fortran-95 (!) constructs.


I think one should go through the pedantic sections in the source and check
whether they still make sense (e.g. give an error for valid F2003, cf. e.g.
PR35882); maybe we should also some more checks? (At least I often forget to
think of the -pedantic option.)


Additionally, one should change (a) "to Fortran 95" into "to the Fortran
standard" and (b) "Valid Fortran 95 programs" into "Programs which are valid
according to the Fortran standard" -- or something like that. In the manual wie
have:

       -pedantic
           Issue warnings for uses of extensions to Fortran 95.
[...]
           Valid Fortran 95 programs should compile properly with or
           without this option.  However, without this option, certain
           GNU extensions and traditional Fortran features are supported
           as well.  With this option, many of them are rejected.

           This should be used in conjunction with -std=f95,
           -std=f2003, or -std=f2008.

--- Comment #2 from sandra at gcc dot gnu.org ---
The manual now documents -pedantic without tying it to Fortran 95, and it
includes a disclaimer 

  Some users try to use @option{-pedantic} to check programs for conformance.
  They soon find that it does not do quite what they want---it finds some
  nonstandard practices, but not all.
  However, improvements to GNU Fortran in this area are welcome.

I think the docs are OK, but is there more to do for this issue in terms of
fixing what -pedantic does?
