Update. cvs/libc-ud-970324-2
1997-03-24 19:58 Richard Henderson <rth@tamu.edu> * stdlib/tst-strtol.c (tests): Correct 64-bit entry. * sysdeps/alpha/bsd-_setjmp.S: Alias _setjmp to __setjmp for change to tst-setjmp.c. * sysdeps/alpha/dl-machine.h: Mirror Roland's recent changes. * sysdeps/i386/dl-machine.h: Correct noexec_p comment. * sysdeps/sparc/dl-machine.h: Likewise. * sysdeps/libm-ieee754/s_remquo.c: Rename {hp,lp} -> {hy,ly}. Add missing qs variable. * sysdeps/libm-ieee754/s_remquof.c: Likewise.
