Synopsis: [DJGPP] preprocessing fortran files by cpp with extension .f
State-Changed-From-To: analyzed->closed
State-Changed-By: neil
State-Changed-When: Thu Jun 20 16:03:46 2002
State-Changed-Why:
This is fixed for 3.2; tradcpp0 is dead (yeh!) and the compiler now does all the preprocessing work, including -remap.

The best would be of course the real implementation of -remap in tradcpp0=
=2E
However I think even ignoring it silently in tradcpp0 could be Ok at leas=
t now
C : option -traditional is unusable for DJGPP as header files are incompa=
tible with it,=20
so no additional harm from silently ignoring this option in tradcpp0
C++ : doesn't use tradcpp0 as far as I looked and I really used -remap
to workaround filename conflicts for libstdc++ header files under plain D=
OS.
Fortran: here we have some trouble as for FORTRAN tradcpp0 is used=20
unconditionally. However there should be no harm from ignoring -remap unl=
ess user=20
explicitly tries to remap file names to be included
=20
So I think it would be sufficient to ignore -remap in tradcpp0 now and ad=
d=20
FIXME note there, to remaind about that, so maybe somebody could add supp=
ort
in future

I added cpp0_only_options and used this spec where needed. I'm including =
diffs
against trunk for common files (except DJGPP target related ones). Unfort=
unatelly=20
I haven't write update for documentation ...
There could be some shift in diffs as I removed unrelated changes for gcc=
=2Ec with text editor

Are you saying that getting tradcpp to recognize and ignore -remap
would fix it? Or does tradcpp require a -remap implementation?

What exactly did you do?

The problem appears when -remap is used in specs in cpp_options. cpp_opti=
ons
settings are common for both tradcpp0 and cpp0. For DJGPP we need -remap
to avoid need to use changed names of include files (DJGPP can be used un=
der
plain MS-DOS when we only have 8+3 filename limitations). -remap is not=20
recognized by tradcpp0 as valid option. Unfortunatelly tradcpp0 and cpp0 =
are
used also directly in specs not only through trad_capable_cpp (otherwise =
I=20
could change there)
I tried to fix that for DJGPP port of gcc-3.0.3, but it required to add=20
options specially for cpp0 only (not for tradcpp0) and to use this new sp=
ec=20
where needed (in cp/lang-specs.h and f/lang-specs.h, gcc.c, etc)
