PR31288: build with gcc14
GCC14 makes -Wmissing-prototypes defaultish on, which triggers on such
gentle-spirited code as:
void foo(void) { }
when you should darn well know to have an exact duplicate declaration
prototype first. Because of course.
void foo(void);
void foo(void) { }
So anyway, with our fondness for -Werror, this broke the stap runtime
autoconf* business, bits of the runtime, bits of the translator.
Probably more stuff as yet unidentified. If your testsuite logs show:
[...]: error: no previous prototype for ‘[...]’ [-Werror=missing-prototypes]
this is probably to blame.
Since this is coming to clang as well, we now get buildrun.cxx to
force -Wmissing-prototypes on all the time, so as to try to notice
occurrences of this problem earlier.
