Authority != Brian !

But I'll try.  Here's how I do it.  To compile, d/l whatever (from the 
tars or cvs), and:

cd ~/opensource/mozilla/js/src
make -f Makefile.ref BUILD_OPT=1 OPTIMIZER="-O3 -fstrict-aliasing 
-ffast-math -funroll-loops -mcpu=7400 -force_cpusubtype_ALL"

(My download is in an opensource directory in my home directory.  Where 
ever you put it, you want to run the make in the js/src directory.)

This, as far as I've experimented, is the best way to compile it for 
speed on OS X.  Watch out with the -ffast-math flag, it's a little 
dangerous but I don't care that much for numerical precision.

Now, here's the part that's tricky, and could use some documentation.  
In js/src/darwin_opt.obj will be libjs.a.  All the .h files you will 
need are in js/src.

Include in your project:

libjs.a (the library)
jsapi.h
jsautocfg.h
jscompat.h
jslong.h
jsosdep.h
jsotypes.h
jspubtd.h
jstypes.h

(That's the tricky part)

And in your main header file, include:

#define XP_UNIX
#define JSFILE

#include "jsapi.h"

There ya go.
