--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> 2012-07-16 08:14:15 UTC --- A quick test of other Fortran compilers shows that this is not a widely supported feature - none of the tried compilers supports it. In C, it falls semantically into the preprocessor, even though it is implemented as compiler feature. In terms of the form, gcc's __FUNCTION__ looks much more like a CPP macro than C99's __func__. (As CPP is not a Fortran-tuned preprocessor, the semantic - when applied to Fortran - is a bit unclear as are features like C99's __func__.)
