Chart of Fortran 2003 Features supported by GNU Fortran
See also Fortran 2008 implementation status
See also TS 29113: Technical Specification on Further Interoperability with C
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:
John Reid, ''The new features of Fortran 2003'', ACM SIGPLAN Fortran Forum '''96''', 10 (2007), which is also available from the Fortran Standards homepage
