* sysdeps/mach/hurd/select.c: Deal with out of order replies during io_select request loop. Handle MACH_RCV_TIMED_OUT error from requests. * hurd/intr-msg.c: If the user passed the MACH_RCV_TIMEOUT option, distinguish MACH_RCV_TIMED_OUT from EINTR. * posix/glob.c (glob): Use realloc to extend strings for GLOB_MARK slash. (glob_in_dir): Don't allocate extra byte here. * sysdeps/i386/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC): Decrement the DT_RELSZ value for the skipped reloc.
