Document pedantic debug mode typo (was Re: GCC 3.4.4)

[Jonathan Wakely]

Mark already approved the patch below (including for 3.4) and I committed
it to 3.4 just now.  Any v3 people have objections to putting it in on
mainline too?

The typo is fixed on the 4.0 branch and mainline but Mark said (in a
private mail) that it's not worth fixing on the 3.4 branch, so the
the affected versions are likely to stay as 3.4.x (for all x) and 4.0.0

2005-05-18  Jonathan Wakely  <redi@gcc.gnu.org>

        * docs/html/debug.html: Explain that _GLIBXX_DEBUG_PEDANTIC must
        be defined for pedantic mode in versions 3.4 and 4.0.0.
