Hi Pat:

The fastest and least time consuming option you may have is to comment
out the offending code.

The other possibility is to rewrite chromium_types.h so that it
references PPC recognized commands which also means that you may have
to become (or be) very familiar with PPC assembler and/or the PPC
command architecture controlling various aspects of the PPC cpu. The
problem with that is that you could make the new file so specific to
the PPC you own that the code may not function on other PPC systems
differently designed.

All the best...
