Thanks for suggestion; I try to remember it for debugging the -fwhole-program issues for which it should be very useful. Though, in this case there is only one UID for "one" - for the external call. The function itself not even generated without the patch. Thus, the linker error says it all :-) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40011
