Recently I discovered, that gfortran FE creates invalid decl trees for exteranl
intrinsics: only return value is added to arg chain, and none of the actual
arguments. This can potentially break much stuff, because of inconsistency of
CALL_EXPR and corresponding fndecl.
This was due to the following TODO in gfc_get_symbol_for_expr():
/* TODO: proper argument lists for external intrinsics. */
