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.
