Update. cvs/libc-ud-970507
* locale/categories.def: Change type of _NL_CTYPE_CLASS_NAMES and _NL_CTYPE_MAP_NAMES field to stringlist. Change name of _NL_CTYPE_CODESET_NAME to "charmap". * locale/localeinfo.h (enum value_type): Add stringlist. * locale/programs/locale.c (show_info): Handle stringlist. * locale/programs/charmap.c (charmap_read): If charmap file is not using the given name try to find it by looking through all available charmap files and compare the code set name. * locale/programs/locale.c (write_charmaps): Also print names of charset in <code_set_name> fields in the files. * elf/ldd.bash.in: Correct translatable strings. * posix/TESTS: Add some more tests for character class matching. * posix/regex.c: Merge with GNU awk version. (regex_compile): Use ISO C/amend 1 functions for character class handling. * posix/regex.h: Merge with GNU awk version. * posix/getopt.c: Declare as master copies. * posix/getopt1.c: Likewise. * posix/getopt.h: Likewise. * sysdeps/unix/sysv/linux/sys/mount.h: Add definitions for option value to mount functions. Patch by a sun <asun@zoology.washington.edu>. * stdio-common/bug4.c (main): Use /tmp/bug4.test for concurrency with other tests. * sunrpc/svc_run.c (svc_exit): New, defined. (svc_run): Test for svc_stop variable. * sysdeps/m68k/s_cexp.c: Rewritten. * sysdeps/m68k/s_cexpf.c: Likewise. * sysdeps/m68k/s_cexpl.c: Likewise.
