Update.

	* configure.in: Use AC_PROG_CC_LOCAL instead of AC_PROC_CC.
	* aclocal.m4: Add AC_PROG_CC_LOCAL which does not fail for
	environments in which linking is not possible at configure time
	(since te libc is just build).
	Based on patches by Marcus G. Daniels <marcus@cathcart.sysc.pdx.edu>.

	* stdlib/random_r.c (__initstate_r): Initialize randomizer type in
	state array only at right place.
	Reported by Sven Verdoolaege <skimo@breughel.ufsia.ac.be>.

	* stdlib/erand48_r.c (__erand48_r): Don't generate numbers in
	[0.5,1.0) but really in [0.0, 1.0).
	Patch by Oliver Gathmann <gathmann@scar.utoronto.ca>.
