* sysdeps/unix/sysv/linux/i386/sysdep.h (PTR_MANGLE): Roll value before cvs/fedora-glibc-20070202T0923
returning. (PTR_DEMANGLE): Real definition now that it's not the same as PRT_MANGLE anymore. * sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise. * string/strerror_l.c: New file. * string/Makefile (routines): Add strerror_l. * string/string.h: Declare strerror_l. * string/Versions: Export strerror_l for GLIBC_2.6. * nscd/connections.c (nscd_run): Don't define MAXKEYLEN here.
