Yes, I've seen this while building binaries for GNU/Linux. Looks like
some weird interaction between libstdc++ and GCC plugin headers.
Specifically, intl.h in GCC defines gettext as a macro which causes
havoc in libintl.h.

Good question. I just checked and none of the GCC plugin headers
actually include intl.h. It also appears that ODB doesn't need
this header (I've just tested with 4.5, 4.6, and 4.7). A lot of
the includes in gcc.hxx are there just because "that's how GCC
excepts them to be".

So, yes, removing intl.h inclusion seems to be the fix. I will
publish a bugfix shortly. Thanks for the report and let me know
if there are any other issues.
