(__process_machine_rela): Pass symbol to dl_reloc_overflow(). 2001-01-02 Ben Collins * time/tzset.c (tzset_internal): Make sure we fall back to UTC if TZ is not set and TZDEFAULT is not present. 2001-01-01 Ben Collins * string/strings.h: Make sure we declare our functions even if string.h is already included, based on whether or not __USE_BSD is defined. 2001-01-02 Ulrich Drepper * dlfcn/dlerror.c (dlerror): Handle call of dlerror() before any other dlopen() and dlsym(). Based on a patch by Ben Collins . 2001-01-02 Andreas Jaeger * dlfcn/errmsg1.c (main): Call dlerror initially.
