On the trunk, I get:

callint.c:895:13: note: each undeclared identifier is reported only once for 
each function it appears in
Makefile:402: recipe for target 'callint.o' failed
make[1]: *** [callint.o] Error 1

and Emacs doesn't ask me for anything when next-error-ing to the file.
(This is on the trunk.)  Are you still seeing this problem?

Hm...  well, I guess it's mostly not interesting, but I could see that
some people would find it interesting sometimes...
