No, support for 4.2 has not been implemented.  I just took a quick look
at doing so.  Unfortunately it looks like a non-trivial task.  Unlike
previous versions GCC 4.2's standard library comes with a whole bunch of
gnu extensions in its code (placement of __attribte__ calls where GCC
3.3 does not support).  In order to support it we will either have to
put hacked-up copies of every header from GCC 4.2 in gccxml (instead of
just a few), or update gccxml to use the GCC 4.2 parser internally.  The
latter will then require updating the support headers for all the other
compilers to be compatible with the newer parser.

I can put this on a todo list but I do not know when I can get to it.
