Bugzilla Bug 162165

(this bug is more an FYI and a reminder for gcc-porting to look into at a
future date when 4.2 is released.  i don't have a fix at this time, but maybe
someone with C++ experience (ie. not me ;)) could shed some light on it.)

building xmlwrapp-0.5.0-r1 with the current GCC 4.2 branch svn will fail.  GCC
4.1.1 works.

Same error, no new information (except that it happens on ~amd64 too).  Yeah,
gcc-4.2.0 is still hard masked, but gcc-config and slots make it easy to try.
=8^)  Yeah, I'll be patient.  (Looking good so far, Ryan, only ~6/600+ packages
failing, <1% fail rate, pretty good this early! =8^)

Fixed. Thanks for reporting.
