As for the compatibility of code built with Xcode 2.5 with that built

Xcode 2.2.1, I think that they should be largely compatible, as my
reading
of the release notes from 2.2.1 to 2.5 is that there have only been
bugfixes and feature enhancements to Xcode's GCC in that time, rather
than
any deliberate compatibility-breaking changes. If that's the case, any
incompatibilities ought to be due to incorrect code produced by Xcode.
Xcode 2.4.1 is largely compatible, and fixes the Intel 64-bit issues
that
makes using Xcode 2.2.1 not work for compiling some ports that want
it...
Xcode 2.5, on the other hand, introduces some breaking changes so that
it
can run in a prefix on Leopard - such as not including
/usr/share/libtool:
