[AUCTeX] Specifiyng the executable paths

[Olivier Lefevre]

I read through the manual but I still can't find how to specify the 
texmf, texmf-local trees or the patsh to the executables when using a 
pre-packaged AUCTeX + emacs installation, i.e., presumably compiled with 
--without-texmf-dir. I went through the options and didn't find anything 
that looked related. I am using teTeX under Cygwin, not MIKTeX.

Another annoyance is that I turend off Font Latex Fontify Sectioning but 
it still shows \chapter entries in bold. How do I shut that down?

Thanks,
