Right. Phil Edwards posted a patch on the libstdc++ list to separate most
of the wide character/advanced locale bits from the base narrow character
bits with an enable flag, ie something like
--enable-wchar_t/--disable-wchar_t. This seems like a sane approach.

The rest of the problems center around the merged libio sources: glibc 2.2
and libstdc++-v3 have (mostly) merged sources now, a codebase that is
substantially different than the libio used for libstdc++-v2. I'm not
quite sure if it'll be easiest to work through the libio ports or to
enable the generic, stdio interface as an alternate. (This is what I'm now
working on.)
