Committed as obvious. Cf. 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45131#c9

The functions are declared as "void" in libgfortran - thus, the FE 
should have the same declaration.

This might be a bug introduced with the recent 
gfc_build_library_function_decl_with_spec annotation, but maybe it is 
older (I have not checked).

Build and regtested on x86-64-linux.
Committed as Rev. 162857.
