[Bug fortran/21302] New: Max line length in free form mode

[pinskia at gcc dot gnu dot org]

I don't know if this is not a bug but I found this will looking into 21300, take the following Fortran free 
formed code:
 if 
(abs(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa).gt.999.d0.or.abs(bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb).gt.99
9.d0.or.abs(cccccccccccccccccccc).gt.999.d0) THEN
endif
 
 end program

Note the if is all on the same line.
We get an error (and a warning with -Wline-truncation) but I don't think free form should have a line 
lenght limit.

See 3.3.1 from the Standard.  "In free source form, each source line may 
contain fomr zero to 132 characters and there are restrictions on where
a statement (or portion of a statement) may appear within a line"

I suppose we could implement a -fline-length=N type option.

Then lets call this an enhancement  but note it blocks compiling OrbFit which works on XLF, Intel's and 
others.

Actually, we already have this, but only for fixed form.  It should be no
problem to generalize this to free form as well.

(From update of attachment 9444)
correct description: it's about free form, not fixed form.
