Autoconf check for XML support?

[Ari Johnson]

I see that there is an OST_CCXX2_DYNLOADER check among the autoconf macros
defined by ost_check2.m4, but no such way to determine if XML support is
built in.  I'm at the point in my project where I need to make the
decision to move to a more portable autoconf/automake build environment,
and that means that I'll need my configure script to check for an
appropriate version of CommonC++ as well as for built-in XML support.
As to incremental XML parsing, I'll just have to assume that people use
the CVS version until an incremented release number exists for the next
release, when I do OST_CCXX2_VERSION.

Would it overclutter things to include an OST_CCXX2_XML check, or is there
perhaps a better way to accomplish this?  Thanks.
