RE: Problems while debugging fortran

["Pierre Muller" <muller@ics.u-strasbg.fr>]

  I am about to commit a similar patch to
recognize the special symbol name used
by GNU pascal compiler.
  I tought about adding a check for
current_language == language_pascal,
but the language is only set if the
program is compiled with debug information
on (will be the case most of the time),
but also only if the main source is recognized
as a pascal source.

  Currently, '.inc', '.p', '.pp' and '.pas'
suffixes are recognized as pascal sources,
but Delphi uses '.dpr' so chances are that
you compile a source that will not be recognized 
as a pascal source and in that case, the
pascal_main_name would not be called at all.
