Subject: * configure.in: Use AC_HAVE_HEADERS to test for sys/time.h, and
X-Git-Tag: archive/raspbian/1%29.2+1-2+rpi1^2~5^2~96397
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=a6eb67976982ccf22d8245e364e0641fdca8e11b;p=emacs.git

* configure.in: Use AC_HAVE_HEADERS to test for sys/time.h, and
	call AC_STRUCT_TM to see what's in time.h.

	* configure.in: Employ quoting stupidity to get the value of CPP
	to expand properly.
