Update.
2001-04-05 David S. Miller <davem@redhat.com>
Add hp-timing support for sparcv9/sparc64 targets.
* sysdeps/sparc/sparc32/sparcv9/hp-timing.c: New file
* sysdeps/sparc/sparc32/sparcv9/hp-timing.h: New file
* sysdeps/sparc/sparc64/hp-timing.c: New file
* sysdeps/sparc/sparc64/hp-timing.h: New file
* sysdeps/sparc/sparc32/sparcv9/Makefile: Build hp-timing.
* sysdeps/sparc/sparc64/Makefile: Likewise.
2001-04-09 Jakub Jelinek <jakub@redhat.com>
* sysdeps/generic/fd_to_filename.h: New file.
* sysdeps/unix/sysv/linux/fd_to_filename.h: New file.
* libio/freopen.c (freopen): If FILENAME is NULL, try to get
filename from the open file descriptor.
* libio/freopen64.c (freopen64): Likewise.
2001-04-09 Bruno Haible <haible@clisp.cons.org>
* misc/error.c (error): fflush stdout also if
error_print_progname != NULL.
(error_at_line): Likewise.
2001-04-07 Bruno Haible <haible@clisp.cons.org>
* intl/gettextP.h (struct loaded_domain): Add codeset_cntr field.
(struct binding): Add codeset_cntr field.
(_nl_load_domain): Add domainbinding argument.
(_nl_init_domain_conv, _nl_free_domain_conv): New declarations.
(_nl_find_msg): New declaration, moved here from loadinfo.h.
* intl/loadinfo.h (struct loaded_l10nfile): Remove domainbinding field.
(_nl_make_l10nflist): Remove domainbinding argument.
(_nl_find_msg): Move declaration to gettextP.h.
* intl/bindtextdom.c (set_binding_values): Initialize ->codeset_cntr
to 0. Increment it when ->codeset is changed.
* intl/dcigettext.c (DCIGETTEXT): Pass binding to _nl_find_msg.
(_nl_find_msg): Add domainbinding argument. Reinitialize the converter
if domainbinding->codeset_cntr has been incremented.
* intl/finddomain.c (_nl_find_domain): Don't pass domainbinding to
_nl_make_l10nflist(). Pass it to _nl_load_domain() instead.
* intl/l10nflist.c (_nl_make_l10nflist): Remove domainbinding argument.
* intl/loadmsgcat.c (_nl_init_domain_conv): New function, extracted
from _nl_load_domain. Append //TRANSLIT also when using libiconv.
(_nl_free_domain_conv): New function, extracted from _nl_unload_domain.
(_nl_load_domain): Add domainbinding argument. Call
_nl_init_domain_conv.
(_nl_unload_domain): Call _nl_free_domain_conv.
* intl/Makefile (distribute): Add tst-codeset.sh, tstcodeset.po.
(test-srcs): Add tst-codeset.
(tests): Depend on tst-codeset.out.
(tst-codeset.out): New rule.
(CFLAGS-tst-codeset.c): New variable.
* intl/tst-codeset.sh: New file.
* intl/tstcodeset.po: New file.

* locale/findlocale.c (_nl_find_locale): Update _nl_make_l10nflist
calls.
