[BZ #3252, BZ #3253]cvs/fedora-glibc-20060925T1535
2006-09-25 Jakub Jelinek <jakub@redhat.com> [BZ #3252] * sysdeps/unix/sysv/linux/powerpc/fchownat.c (fchownat): Handle only fchownat syscall and __ASSUME_LCHOWN_SYSCALL case inline, call __{,l}chown to handle the rest. * sysdeps/unix/sysv/linux/i386/fchownat.c (fchownat): Handle only fchownat syscall and __ASSUME_32BITUIDS case inline, call __{,l}chown to handle the rest. * sysdeps/unix/sysv/linux/sparc/sparc32/fchownat.c: Include i386/fchownat.c. * sysdeps/unix/sysv/linux/s390/s390-32/fchownat.c: Likewise. * sysdeps/unix/sysv/linux/sh/fchownat.c: Likewise. [BZ #3253] * posix/glob.c (glob_in_dir): Don't alloca one struct globlink at a time, rather allocate increasingly bigger arrays of pointers, if possible with alloca, if too large with malloc. 2006-09-24 Jakub Jelinek <jakub@redhat.com> * sysdeps/powerpc/fpu/libm-test-ulps: Updated. * sysdeps/ieee754/ldbl-128/s_lrintl.c (__lrintl): Fix 2 typos.
