+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.
+
2001-01-31 Ulrich Drepper <drepper@redhat.com>
+ * elf/elf.h (SHT_CHECKSUM): New definition.
+
* posix/fnmatch_loop.c: Remove incorrect reverse condition in
[. .] matching. Patch by Isamu Hasegawa <isamu@yamato.ibm.com>.
+ * posix/tst-fnmatch.input: Add tests for [. .] in locales.
