non-void function [-Wreturn-type]"

test case
With the current trunk, I get:
$ g++ -S -Wall bogus_warn.cc
bogus_warn.cc: In function ‘int nsp::test(nsp::LookupResult*)’:
bogus_warn.cc:44:1: warning: control reaches end of non-void function
[-Wreturn-type
While using g++ 4.6, no warning is shown.
Looking at my builds (no warranty):
No warning with: 2011-11-06 (Rev. 181031)
Warning with: 2011-11-11 (Rev. 181283)
