Question/problem related to _Bool in type_traits.h

Sometime in the past, specifically according to gcc/ChangeLog.2 
(8/29/99), Zack Weinberg added a #define for '_Bool' to stdbool.h to 
define it as the type 'bool'.  This means that now with gcc 3.x you 
can no longer include both stdbool.h and libstdc++'s type_traits.h in 
the same compilation because type_traits.h defines a _Bool template. 
It didn't in 2.95.x days which is why this wasn't a problem until now 
with gcc 3.x.

Does anyone have a suggested (permanent) fix for this problem.  For 
the time being I've added a #undef _Bool just before the template 
definition in type_traits.h.
