The following is invalid standard Fortran 77/90/95/2003 syntax,
volatile /C/
however, it seems to be a not uncommon Fortran 77 vendor extension, supported
by g77, ifort, sunf95, openf95, ...

We need to add a "volatile_" attribute to COMMON; and, either add the VOLATILE
attribute to all its symbols in resolve.c or change the if block in
trans-common.c, which has been added in PR 35037.

------- Comment #3 from dfranke at gcc dot gnu dot org 2010-05-09 19:28 -------
Since PR35037 we can have VOLATILE variables in COMMON blocks. But VOLATILE
COMMON blocks are still unsupported (gcc version 4.6.0 20100509 (experimental)
(GCC)). Demand is low, besides this PR, there's nothing in the ML. Even if
supported by g77 - WONTFIX (maybe with a note in the docs)?
