He didn't use the --enable-gcc-warnings option; warnings were enabled 
automatically because he built from a Git checkout rather than from the 
snapshot tarball.As it's inevitable that people will build from git 
rather than from tarballs, I installed the attached patch to try to fend 
off reports like this in the future. It is annoying to maintain approved 
GCC version numbers in configure.ac; perhaps there's a better way to do it.

Tested on Solaris 10 sparc with its bundled GCC 3.4.3, which is so old 
that the Solaris assembler warns about GCC's use of DCTI couples, a 
SPARC feature that was deprecated in 2005! Luckily I was testing on the 
circa-2000 hardware that is still our central departmental server.
