load, so as to work on both 32-bit and 64-bit. Remove unnecessary casts. Align __libc_stack_end to 8 bytes. 2002-09-20 Roland McGrath <roland@redhat.com> * sysdeps/powerpc/fpu/s_lrint.c: Use strong_alias/weak_alias macros instead of asm for lrintf, __lrintf aliases. * sysdeps/powerpc/fpu/s_lrint.c (__lrint): Change union long array to int array for 32-/64-bit compatibility.
