2000-11-20 Ulrich Drepper <drepper@redhat.com> * csu/gmon-start.c: Always have prototype for __gmon_start. * csu/version.c: Add prototypes for __libc_print_version and __libc_main. * iconv/gconv.c: Include gconv_int.h and gconv.h. * iconv/gconv.h (struct __gconv_step): Remove const from __from_name and __to_name. * iconv/gconv_builtin.h: Add ASCII module definitions. * iconv/gconv_conf.c (__gconv_path_elem): Remove const. (add_module): Add cast to avoid warning. Rework construction of strings for new module. * iconv/gconv_db.c (__gconv_alias_compare): Make s1 and s2 const. (derivation_compare): Likewise. * iconv/gconv_dl.c (do_release_shlib): Remove const from nodep. (__gconv_release_shlib): Cast do_release_shlib as parameter for twalk. * iconv/gconv_int.h (__gconv_path_elem): Remove const. (struct gconv_alias): Remove const from fromname and toname. * iconv/gconv_simple.c: Include gconv_builtin.h to get prototypes for loop functions. (internal_ucs4_loop): Use correct const-ness. (ucs4_internal_loop): Likewise. (internal_ucs4le_loop): Likewise. (ucs4le_internal_loop_single): Likewise. * iconv/gconv_trans.c (__gconv_transliterate): Make from_idx, from_tbl, to_idx, to_tbl, winbuf, winbufend const. Change casts in assignments appropriately. (struct known_trans): Remove const from fname. (trans_compare): Make s1 and s2 const. * iconv/loop.c (LOOPFC): Make outend parameter const. Add cast to avoid warning. * iconv/skeleton.c: Remove cast in calls of loop functions. * iconvdata/gconv-modules: Remove US-ASCII definitions. * iconvdata/iso646.c: Remove US_ASCII support. * include/set-hooks.h (DEFINE_HOOK): Also generate prototype. * include/unistd.h: Add __libc_check_standard_fds prototype. * string/bits/string2.h (__mempcpy_args): Add const to casts. * sysdeps/generic/initfini.c: Add prototypes for dummy, _init, and _fini. * sysdeps/generic/libc-start.c: Add prototype for __libc_start_main. * sysdeps/i386/i486/bits/string.h (strcmp): Add const to casts. * sysdeps/unix/sysv/linux/dl-osinfo.h (dl_fatal): Add cast to avoid warning. * sysdeps/unix/sysv/linux/init-first.c: Add prototypes for __libc_init_first and _dl_start. * sysdeps/unix/sysv/linux/mips/clone.S: Fix comments.
