Sorry, but I think -WError is a good idea. 

It can easilty be disabled on a per-file basis with -DWERROR=

Hmm. Jason has also asked me about this. CVS gcc, as of today, on RH 
6.2/intel and --enable-libstdcxx --enable-debug --enable-cshadow works 
fine for me (meaning I get a build, and one test failure in 'make check')

Can you please be more specific?

Also, jason, your testcase does not error out on me, even with -Wall -Werror.
