staging headers patch, next iteration

[Phil Edwards]

Here's the complete patch, sans regenerated files.  A full aclocal &&
autoconf && autoheader && automake should be done after putting this
in place.  Also, since 'cvs diff' won't do the 'patch against /dev/null'
thing properly, and 'patch' won't create a new file from such a diff anyhow,
the include/Makefile.am is attached separately.  I /think/ that's the only
file which still needs tweaking for gthr*.
