Thu Oct 10 14:00:01 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/i386/sigcontext.h: Moved file... * sysdeps/unix/sysv/linux/sigcontext.h: ...to here. So the Alpha people find a correct file. * sysdeps/libm-ieee754/w_cabs.c: We cannot make __cabsl simply an alias of __cabs since the structures have different names. * sysdeps/libm-ieee754/w_log10.c: Fix typo in weak_alias. Reported by Matthew Jacob <mjacob@feral.com>. simply a wrapper around the <linux/elfcore.h> file since the
