(2) Shared DO termination and termination
on a statement other than END DO or CONTINUE
(6) DATA statements amongst executable statements

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.)

(In reply to comment #3)
 The warnings about deleted features can be turned off via -std=legacy, and are
 turned into errors by -std=f95 and above.

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.

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

--- 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.

(In reply to comment #1)
 In a similar vain: One could introduct an option to disable warning for the
 deleted features

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 speci#64257;ers.
 (5) H edit descriptor.

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.
