Subject: * dispnew.c (getenv): Extern declaration deleted; this is done in
X-Git-Tag: archive/raspbian/1%29.2+1-2+rpi1^2~5^2~96549
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https:/www.github.com/%22bookmarks:///%22http:/www.example.com/cgi/%22https:/www.github.com/%22bookmarks:/?a=commitdiff_plain;h=5de9f849e8f24802a873fcb16785558aca28a3e3;p=emacs.git

* dispnew.c (getenv): Extern declaration deleted; this is done in
	config.h.

	* dispnew.c (init_display): Compare the return value of getenv to
	zero before setting display_arg, instead of just using the pointer
	as a truth value.
