Thanks for the patch - I think that these header files should be in
there, although I'm still not sure why their absence was causing this
problem, because the P2X*.hxx are generated from the same rule, and they
were getting built first (was this a parallel build with make -jX (where
X is a number greater than 1)?). I will look into this at some point.
The hourly builds for Mac OS X do work, although it would have been a
long time since the headers needed to be regenerated.

Yes, PCEnv needs a number of special patches to fix various things like
RDF parsing (Mozilla's internal RDF API isn't conformant with the latest
RDF standards) and, as you have found, to work around bugs in the Darwin
linker that cause problems for certain XPCOM components (although even
someone who works on the Apple compiler team and also Mozilla doesn't
know exactly what that error message means!).

The version of Mozilla you need is maintained in a git repository on my
system, and occasionally gets merged from Mozilla's CVS, and pushed into
our public Subversion from git, at
https://svn.physiomeproject.org/svn/physiome/mozilla/trunk

Kind regards,
Andrew
