Description of problem:
When building libvirt RPMs we're seeing warnings generated from the GCC that dtrace runs

This can be reproduced standalone as follows:

$ CFLAGS=-Wall /bin/dtrace -o libvirt_probes.o -G -s libvirt_probes.d
/tmp/tmpca8bLT.c:1:8: warning: return type defaults to ‘int’ [-Wreturn-type]
/tmp/tmpca8bLT.c:1:8: warning: ‘__dtrace’ defined but not used [-Wunused-function]
/tmp/tmpca8bLT.c: In function ‘__dtrace’:
/tmp/tmpca8bLT.c:1:1: warning: control reaches end of non-void function [-Wreturn-type]

The first line of that file is

static __dtrace () {}

Which is a bogus signature - should be   static int __dtrace(void) {} though that still won't make the -Wunused-function warnings go away.


Version-Release number of selected component (if applicable):
systemtap-2.0-4.fc18.x86_64
