Chart of Fortran 2003 Features supported by GNU Fortran
When the question which Fortran 2003 feature is implemented in which compiler, came up in comp.lang.fortran, the idea was born to create a chart of the features supported by the different compilers; the question was sent to the j3-Fortran list and the result was the following paper:
Update: ACM SIGPLAN Fortran Forum '''26''', 2 (2007) (part of the Frontmatter; contains the status of more compilers)
A version from August 2008 can be found here (unrestricted access).
April 2009: ACM SIGPLAN Fortran Forum '''28'''(1), 26 (2009)
August 2009: ACM SIGPLAN Fortran Forum '''28'''(2), 15 (2009)
Latest Version of December 2009: ACM SIGPLAN Fortran Forum '''28'''(3), 32 (2009)
which follows the feature listed in the following paper
John Reid, ''The new features of Fortran 2003'', ACM SIGPLAN Fortran Forum '''96''', 10 (2007), which is also available from the Fortran Standards homepage
There is now also a list for the implemention status of Fortran 2008 features
Implemented 2003 feature in GNU Fortran compiler
For other compilers see the Fortran Forum paper cited above. (These are not the only new features of Fortran 2003 though.)
