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__.)
