OpenC++ sources does not conform to namespaces scheme mandated by C++ standard
(i.e. that standard library components live in 'std' namespace). OpenC++
DOES NOT compile with gcc>=3.0. It is not difficult to fix and
somebody has already done it, but nobody had enough will to check it in.
Go to OpenC++ project page at www.sf.net and search the archive of
opencxx-user, the link to the gcc-3.0 compatible version has been posted
here. If you can spare some time to merge the changes with HEAD revision
and check it in, the heavens will thank you (and I will join too).

*PLEASE* work on CVS HEAD.

2.5.12/2.5.13 is difficult to maintain because of code duplication in its
build system. OpenC++ project does not have resources to maintain it.
Moreover, 2.5.12 does not include test harness nor test suite, which
disables reliable development, because you have no means to verify if your
contribution breaks the current functionality. It is likely that your
otherwise very valuable work will not be useful if you stick to 2.5.12 .
