[Patch/fortran] Add documentation section about implemented F2003 features

[Janne Blomqvist]

Hello,

following patch adds a section to gfortran.texi about implemented
F2003 features.

I also removed the mention of eventual support of Fortran 90. IMHO the
inability of F95 allocatables to leak memory, as opposed to the F90
ones, is sufficient reason alone to actively discourage users from
using F90.

Also, strictly speaking the FLUSH statement is not yet implemented,
although it looks like it will go in in the not too distant future (no
hurry Steve, I understand you're busy!). If I have missed any other
F2003 features, please notify me (I basically just grepped for
GFC_STD_F2003 in my current tree).

ChangeLog and patch follows:


2005-08-03  Janne Blomqvist  <jblomqvi@cc.hut.fi>
