I can also add something to extensions, but I think it makes more sense
to have it in:

"10 Standards [...]
10.1 Fortran 2003 status
Although GNU Fortran focuses on implementing the Fortran 95 standard for
the time being,
a few Fortran 2003 features are currently available.
[...]
* Namelist input/output for internal files.
* The VOLATILE statement and attribute."

See http://gcc.gnu.org/ml/gcc-patches/2006-11/msg00400.html
Tested with make info and make pdf.


Should I also add something to extensions?

PS: I have problems making gcc.pdf (gfortran.pdf is ok). I get the
following error message, can anyone reproduce this?

make[2]: Entering directory `/projects/tob/gcc-build/gcc'
texi2pdf -I . -I /home/tob/projects/gcc/gcc/doc -I
/home/tob/projects/gcc/gcc/doc/include -o doc/gcc.pdf
/home/tob/projects/gcc/gcc/doc/gcc.texi
[...]
/home/tob/projects/gcc/gcc/doc/invoke.texi:1079: I can't find file `'.

With invoke.texi:1079:
@include @value{srcdir}/../libiberty/at-file.texi

If I read the texinfo documentation correctly, this should work (and it
does with makeinfo [info, html]), but with texi2{html,dvi,pdf} it does
not. (This is a new problem, I have texinfo-4.8-36. If no one can
reproduce it, I will fill a bugreport at openSUSE.)
