Why do most Fortran 2008 features (e.g., NEWUNIT, DO CONCURRENT) have the green color notation in Intel Fortran Compiler XE 13.1 User and Reference Guide? The documentation says the green color convention "Indicates extensions to the Fortran 2003 and Fortran 2008 Standards. These extensions (non-standard features) may or may not be implemented by other compilers that conform to the language standard." But it is unclear what extensions are in play for such features such as NEWUNIT, DO CONCURRENT, etc. - the description of these features seems to match those in ISO/IEC 1529-1:2010 for Fortran 2008. So is there some aspect of the implementation in Intel compiler that is different from the standard? Am I missing something?
