Hello all, hi Gerald,

attached you find an update for the GCC 4.6 release notes on the
webserver and for the Fortran 2008 status section of gfortran.texi

I intent to commit it as obvious but I would be happy to hear
comments to about the patch (or also other items in those files).

Current version:
- http://gcc.gnu.org/gcc-4.6/changes.html#Fortran
- http://gcc.gnu.org/onlinedocs/gfortran/Fortran-2008-status.html

Note to gfortraners: I have realized that the -Wconversion/-Wconversion-extra
change was not documented in the release notes (or the Wiki).
Is anyone aware about anything else which is missing from the
release notes?

Additionally: Does anyone volunteer to update the Fortran 2003
status in the manual? It is badly outdated:
http://gcc.gnu.org/onlinedocs/gfortran/Fortran-2003-status.html

Tobias
