Update.
2003-12-17 Jakub Jelinek <jakub@redhat.com> * malloc/mtrace.c (tr_old_memalign_hook): New variable. (tr_memalignhook): New function. (mtrace): Register tr_memalignhook. (muntrace): Deregister tr_memalignhook. * malloc/malloc.c (__posix_memalign): If __memalign_hook != NULL, call it directly instead of memalign_internal. 2003-12-17 Ulrich Drepper <drepper@redhat.com> * misc/mntent_r.c: Change encoding to match recently change decoder. Patch by Alexander Achenbach <xela@slit.de>. 2003-12-16 Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h: Correct definition of vrregset_t. 2003-12-16 Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/unix/sysv/linux/powerpc/sys/procfs.h [!__PPC64_ELF_H]: Extent conditional to include typedef elf_vrreg_t. 2002-12-17 Paolo Bonzini <bonzini@gnu.org> * posix/regexec.c (re_search_internal): Limit search to the beginning of the buffer if the initial states are empty for contexts that do not include CONTEXT_BEGBUF or, if !preg->newline_anchor, that do not include any one of CONTEXT_BEGBUF and CONTEXT_NEWLINE.
