Supported Fortran 2003 features

[Tobias Burnus <burnus at net-b dot de>]

Hi,

the next edition (April) of "ACM Fortran Forum" will contain a list
about supported compiler features, collected by Ian Chivers and Jane
Sleightholme. (http://portal.acm.org/browse_dl.cfm?idx=J286)

For the list I sent in, cf.
http://gcc.gnu.org/ml/fortran/2007-02/msg00081.html
For the questions, cf. ftp://ftp.nag.co.uk/sc22wg5/N1601-N1650/N1648.pdf

Please proof read below (copied from the PDF version, omitting the other
compilers).

Thanks,

Tobias
