I very strongly second what stevenb said:

  GCC 3.2 claims many things, but any GCC that has the old C++ parser
  has known non-conformances. IMHO we should only support GCC versions
  with the "new" C++ parser, i.e. GCC 3.4 and up.

Expecting people to bootstap with GCC 3.2 to check it doesn't barf on some
perfectly valid piece of C++ is unreasonable.  If people didn't bootstrap with
3.2 then incompatibilities would creep in and not be found, so claiming that
using 3.2 is possible would be a lie.  Just say no.
