For just about every file I compile I get:
../../dist/include/jsapi.h: In function ‘JSBool JSID_IS_ZERO(jsid)’:
../../dist/include/jsapi.h:332: warning: NULL used in arithmetic

Also happens on Mac OS X.

Attachment: fix: s/NULL/0/

Trivial fix: just replace
   JSID_BITS(id) == NULL
with
   JSID_BITS(id) == 0

Other preexisting macros in the same file already check against 0.  This just makes the body of this new macro "JSID_IS_ZERO" (added yesterday) match that convention.

fix: s/NULL/0/

Requesting approval to land. Trivial fix (s/NULL/0/ one-liner), fixes a very-spammy build warning introduced yesterday.

ah, thanks -- I didn't realize this was an issue on tracemonkey too, since bug 601457 just mentioned an m-c checkin.
