[PATCH] don't forbid brace groups with g++ 4.2.2

I find I can allow brace groups with g++ 4.2.2 without "insane errors ensue"ing.

In turn, this silences some compiler warnings with g++ which are due to the 

non-brace-group form of some *REFCNT_inc macros.



The comment "g++ allows them but seems to have problems with them" appeared in

August 2006, and could be from g++ 3.* or g++ 4.0, so I have tried to set the

limit of allowable g++ versions at 4.2.
