Subject: Omit duplicate definitions no longer needed with gcc -g3.
X-Git-Tag: emacs-24.3.90~173^2~9^2~176
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=0d879dca4648aa15bd3c9ae4ff8b6c39e0c07326;p=emacs.git

Omit duplicate definitions no longer needed with gcc -g3.

* lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
(VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
Define only as macros.  There's no longer any need to also define
these symbols as enums or as constants, since we now assume
gcc -g3 when debugging.
