Update.
2004-03-14 Ulrich Drepper <drepper@redhat.com> Make the non-_l functions wrappers around the _l functions. * include/monetary.h: Declare __vstrmon_l. * include/string.h: Add libc_hidden_proto for __strcoll_l and __strxfrm_l. * include/time.h: Define ptime_locale_status. Declare __strptime_internal. * include/wchar.h: Add libc_hidden_proto for __wcscoll_l and __wcsxfrm_l. * stdlib/strfmon.c: Move the code to strfmon_l.c. Add little wrapper around __vstrfmon_l. * stdlib/strfmon_l.c: Add real implementation. Split into new function __vstrfmon_l to allow calling it from strfmon. * stdlib/strtod.c: Move real code to strtod_l.c and add wrapper. * stdlib/strtod_l.c: Add real implementation. * stdlib/strtof.c: Adjust to changed strtod.c. * stdlib/strtof_l.c: Include strtod_l.c now. * stdlib/strtold.c: New file. * stdlib/strtold_l.c: Removed. * string/strcoll.c: Move real code to strcoll_l.c: Add wrapper. * string/strcoll_l.c: Add real implementation. * string/strxfrm.c: Move real code to strxfrm_l.c: Add wrapper. * string/strxfrm_l.c: Add real implementation. * sysdeps/generic/strtol.c: Move real implementation to strtol_l.c. Add wrappers. * sysdeps/generic/strtol_l.c: Add real implementation. * sysdeps/generic/strtold.c: Removed. * sysdeps/generic/strtold_l.c: New file. * sysdeps/generic/strtoll_l.c: Include strtol_l.c now. Adjust #defines. * sysdeps/generic/strtoul_l.c: Likewise. * sysdeps/generic/strtoull_l.c: Likewise. * sysdeps/generic/wcstol_l.c: Likewise. * sysdeps/generic/wcstoll_l.c: Likewise. * sysdeps/generic/wcstoul_l.c: Likewise. * sysdeps/generic/wcstoull_l.c: Likewise. * sysdeps/ieee754/ldbl-128/strtold.c: Removed. * sysdeps/ieee754/ldbl-128/strtold_l.c: New file. * sysdeps/ieee754/ldbl-96/strtold.c: Removed. * sysdeps/ieee754/ldbl-96/strtold_l.c: New file. * sysdeps/m68k/strtold.c: Removed. * sysdeps/m68k/strtold_l.c: New file. * time/strftime.c: Move real code to strftime_l.c. Add wrapper. * time/strftime_l.c: Add real implementation. * time/strptime.c: Move real code to strptime_l.c. Add wrapper. * time/strptime_l.c: Add real implementation. * time/wcsftime.c: Simplify since only wrappers are defined in strftime.c. * time/wcsftime_l.c: Include strftime_l.c. * wcsmbs/wcscoll.c: Simplify since the file is not used by wcscoll_l.c anymore. * wcsmbs/wcscoll_l.c: Include strcoll_l.c. * wcsmbs/wcsxfrm.c: Simplify since the file is not used by wcsxfrm_l.c anymore. * wcsmbs/wcsxfrm_l.c: Include strxfrm_l.c. * wcsmbs/wcstod.c: Prepare to include new strtod.c. * wcsmbs/wcstod_l.c: Include strtod_l.c. * wcsmbs/wcstof.c: Prepare to include new strtof.c. * wcsmbs/wcstof_l.c: Include strtof_l.c. * wcsmbs/wcstold.c: Prepare to include new strtold.c. * wcsmbs/wcstold_l.c: Include strtold_l.c. * locale/uselocale.c: Use _NL_CURRENT_LOCALE instead of __libc_tsd_get. * sysdeps/generic/strcasecmp.c: Optimize a bit. It's better to get a reference to the current locale and then use the _l functions. * sysdeps/generic/strncase.c: Likewise.
