Subject: Do not worry about whether locale.h is includable
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=3307df444410797b97f5026424a7e6cec18de07c;p=emacs.git

Do not worry about whether locale.h is includable

* src/emacs.c, src/lread.c, src/sysdep.c: Remove preconditions
from including locale.h.  It was standardized in C89, is universal
now, and some code already assumes it.

(cherry picked from commit d2b847d2911218380d1640dea81d6e72d4a7dc7c)
