* sysdeps/unix/sysv/linux/init-first.c (init): Remove [! SHARED]

Browse Source 
conditional from __libc_multiple_libcs access.  Remove kludge for weak
	symbol access with old compilers we no longer support.
	* sysdeps/unix/sysv/aix/init-first.c (init): Likewise.
	* sysdeps/generic/libc-start.c (__libc_start_main): Likewise.

2002-10-24  Roland McGrath  <roland@redhat.com>

	* sysdeps/generic/ldsodefs.h (struct rtld_global): New member
	`_dl_tls_static_used'.
	(TLS_STATIC_MIN): New macro.
	* sysdeps/generic/libc-tls.c (_dl_tls_static_used): New variable.
	(__libc_setup_tls): Initialize it.
	* sysdeps/generic/dl-tls.c (_dl_determine_tlsoffset): Likewise.
	* elf/dl-reloc.c [USE_TLS] (allocate_static_tls): New function.
	(CHECK_STATIC_TLS): Use it.
	* elf/dl-close.c (_dl_close): Adjust _dl_tls_static_used when the
	closed objects occupied a trailing contiguous chunk of static TLS area.
