Subject: configure.in: Check for unistd.h as well.
X-Git-Tag: prereleases/egcs-1.1-prerelease~1166
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=3fe97d74adf47f126ba3c19e633826eeb95c2662;p=thirdparty%2Fgcc.git

configure.in: Check for unistd.h as well.

�
	* configure.in: Check for unistd.h as well.
	* configure: Rebuild.
	* config.in: Rebuild.
	* getpagesize.c (GNU_OUR_PAGESIZE): Use sysconf only if _SC_PAGESIZE
	is defined in unistd.h. Reformat conditional block for easier reading.
	* config.table (shared): Default to no if ${enable_shared}
	is unset or empty; this logic is used by the toplevel
	configure scripts, too.
