Apparently, the fix in

	http://gcc.gnu.org/ml/gcc-patches/2003-01/msg00209.html

wasn't good enough - see example below.

This seems to be related.

NEW PROBLEM:
----
The option -ffixed-line-length-none is dropped after using -x
f77-cpp-input.
---

This does not work now (g77 version 3.3 pre-release out of cvs), but did
work under g77 version 2.96 (comes with RedHat 7.3).

A small test case to demonstrate is attached.

ll.f :

C this test case demonstrates using CPP to create
C source lines longer than a standard punch card.
#include "pi.h"
       IMPLICIT NONE
       REAL*4 AAAAAAA
       AAAAAAA =  ( PI * PI  * PI)
       PRINT*,AAAAAAA
       END

and pi.h :
#define PI 3.14159265358979323846

So the line is forced over column 72 by the macro expansion. 

The compile error looks like this:

/usr/local/bin/g77 -ffixed-line-length-none -x f77-cpp-input ll.f
ll.f: In program `MAIN__':
ll.f:6: 
          AAAAAAA =  ( 3.14159265358979323846 * 3.14159265358979323846  * 3
                     1                                                     2
Missing close parenthese at (2) needed to match open parenthese at (1)

I will enter this into the gcc bugs database if that is what needs to be
done, unsure if this was a continuation of the previous PR or a new one.
