gcc svn build fails due to -Werror; how to set option

[Tim Prince <n8tm@xxxxxxx>]

In attempts to build the gomp_4.0 branch from svn (on CentOS 6.2), I 
find that I must remove the -Werror option in STRICT_WARN.  I don't find 
documented how this should be done (in configure ?).  I can get past it 
by repeatedly modifying gcc/Makefile, but this seems wrong.
I have little interest at this stage in finding out why it triggers 
-Werror=maybe-uninitialized in typeck.c; I'd only like to build the gcc 
to see if it does anything interesting with OpenMP 4.
