1997-05-26 22:51 Ulrich Drepper <drepper@cygnus.com> * 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>. * time/scheck.c (scheck): Make 2nd parameter const. * time/private.h: Likewise. 1997-05-26 18:58 Ulrich Drepper <drepper@cygnus.com> * 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>. 1997-05-22 12:50 Eric Delaunay <delaunay@lix.polytechnique.fr> * shlib-versions: Provide Linux/SPARC defaults. 1997-05-26 15:00 Matthias Urlichs
