Update.
2001-02-01 Ulrich Drepper <drepper@redhat.com> * Makerules (build-shlib): Add $(extra-B-$(@F:lib%.so=%).so). * configure.in: Test for -z initfirst linker option. * config.make.in: Add have-z-initfirst. * elf/dl-init.c (_dl_init): Split out actual initialization code in new function call_init. If _dl_initfirst is non-NULL initialize first. * elf/dl-load.c (_dl_map_from_fd): If DF_1_INITFIRST flag is set remember object in _dl_initfirst. * elf/soinit.c: Remove special support for calling __pthread_initialize_minimal. * conform/conformtest.pl: Add missing $prepend in type test. * elf/elf.h (SHT_CHECKSUM): New definition. * posix/tst-fnmatch.input: Add tests for [. .] in locales.
