AFAICT this PR is not a regression and in principle should only be applied to the coming gcc-7 branch. The "port" maintainers (fink or macports for OS X) may want to apply the patch on their distros.

Could the corresponding code not be ganked and fitted to > this application? Since GCC is a "C-centered" compiler, so to speak, the middle end is surely able to handle unions (if the Fortran front end is taught to support them). > It would make sense to me to allow UNION/MAP inside UDTs Yes! (if by UDTs you mean "derived types", DT, as they are called in the Fortran standard) > as well as RECORDs and STRUCTUREs. No. I would say the STRUCTURE/RECORD syntax should not be used at all, since it can be replaced by standard DTs. IMHO, UNION/MAP would be a useful extension to standard Fortran, while STRUCTURE/RECORD would not (and should not be implemented in gfortran).

From an API standpoint it cannot afaik. A suggestion for the former lies here http://stackoverflow.com/questions/14733238/convert-fortran-dec-union-map-extensions-to-anything-else

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56226 --- Comment #2 from russelljbrennan at gmail dot com 2013-02-07 13:31:16 UTC --- It seems to me that the UNION/MAP pair is analogous to a basic form of a c/c++ union of structs. Could the corresponding code not be ganked and fitted to this application? I did notice in the IBM link that you provided that unions are only defined in an enclosing record structure... RECORDs and STRUCTUREs are easily replace with UDTs. It would make sense to me to allow UNION/MAP inside UDTs as well as RECORDs and STRUCTUREs.

However, if someone volunteers to work on this, it might happen sooner.
