Chart of Fortran 2003 Features supported by GNU Fortran

When the question which Fortran 2003 feature are 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 series of Fortran Forum articles, listed below.

The listed items follow the sections in the following writeup:

The Fortran Forum articles:

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.)
