Building libstdc++-v3 and -WError

[Theodore Papadopoulo]

I appreciate the concern of having the library free of any warnings,
but isn't -WError a little too hard...

Every time I tried to add --enable-libstdcxx-v3 lately when building gcc the 
compilation is aborted during libstdc++-v3. This time it's for some very
``stupid'' warning, 
that is even not of the responsibility of libstdc++-v3.
Basically the linux c library iswctype macro tests whether an unsigned in >=0
and warns that this is always true which is OK but aborts !! 

Would it be possible to remove -WError from the Makefile by 
restricting it to some maintainer mode, or maybe there is a better 
solution ? Most people cannot play with their system headers to avoid 
such things.

 	Thank's
