* hurd/hurdselect.c (_hurd_select): Fix
MACH_MSG_TYPE_INTEGER_T -> integer_t in sizeof. Use a union rather than casts to compare mach_msg_type_t as int. 2002-03-25 Roland McGrath <roland@frob.com> * hurd/hurdchdir.c (_hurd_change_directory_port_from_name): Don't check off the end of NAME when it's shorter than 2 chars. Reported by Ognyan Kulev <ogi@fmi.uni-sofia.bg>. 2002-03-17 Roland McGrath <roland@frob.com> * sysdeps/mach/hurd/i386/sys/io.h: New file. * sysdeps/mach/hurd/i386/ioperm.c: New file. * sysdeps/mach/hurd/i386/Dist: Add them. * sysdeps/mach/hurd/i386/Versions (libc: GLIBC_2.2.6): New set, add ioperm. * sysdeps/mach/configure.in: New check to set HAVE_I386_IO_PERM_MODIFY. (mach_interface_list): Check for mach_i386.defs. * config.h.in (HAVE_I386_IO_PERM_MODIFY): #undef it. * sysdeps/mach/configure: Regenerated.
