* [Bug fortran/40881] New: warn for obsolescent features

gfortran should have a flag ("-Wobsolescent" or similar) to turn on warnings
about obsolescent features. These features are listed in chapter B.2 in the
Fortran standard. They are not forbidden by the standard, but are redundant and
can be replaced by newer and better features.
The standard also notes the possibility that they may be removed in the future.
Therefore gfortran should discourage their usage, just like the standard does.
Obsolescent features in Fortran 2003 are:
(1) Arithmetic IF
(2) Shared DO termination and termination
on a statement other than END DO or CONTINUE
(3) Alternate return
(4) Computed GO TO statement
(5) Statement functions
(6) DATA statements amongst executable statements
(7) Assumed length character functions
(8) Fixed form source
(9) CHARACTER* form of CHARACTER declaration
The -Wobsolescent flag does not have to go into -Wall (maybe -Wextra?)

In a similar vain: One could introduct an option to disable warning for the
deleted features (such as using real-valued loops) - currently, those warnings
alre always printed, hiding other warnings in all the output.
By the way, in the standard, obsolescent parts appear in smaller print.

Good point. In particular these are:
(1) Real and double precision DO variables.
(2) Branching to an END IF statement from outside its block.
(3) PAUSE statement.
(4) ASSIGN and assigned GO TO statements and assigned format specifiers.
(5) H edit descriptor.

------- Comment #3 from janus at gcc dot gnu dot org 2009-07-30 08:20 -------
In principle warnings for obsolescent features are already there (cf.
GFC_STD_F95_OBS). They are issued with -std=f95 or above, which does work e.g.
for arithmetic if. However, there is no warning for alternate return (maybe
others are missing as well).
The warnings about deleted features can be turned off via -std=legacy, and are
turned into errors by -std=f95 and above.

------- Comment #5 from janus at gcc dot gnu dot org 2009-08-02 11:13 -------
r150349 adds warnings for:
* alternate return
* computed goto
* statement functions
* old-style character lengths
Before we already had:
* arithmetic if
* assumed-length character functions
Which leaves the following warnings unimplemented:
* shared DO termination
* DATA statements among executable statements
* fixed form source

I think I would like to see a way to disable them with -std=gnu. Sometimes one
wants to have as many warnings as possible, except for one class of warnings,
which appears often in legacy programs. Thus -W(no-)deleted-std or something
like that (on for -std=gnu, off for -std=legacy) would be sometimes useful, if
one wants to get an old program running.

Ahh, I'd like to see that one!

That's your PR40165 ;)

Those two are now fixed.
I think the only missing item is the following:
> (8) Fixed form source
(I think one should consider to add some flag to silence the fixed-form
warning. At least I know a lot of code, which is in fixed form but otherwise
warning free.)
