2000-11-15  Jakub Jelinek  <jakub@redhat.com>

	* dlfcn/default.c (main): Add test for dladdr of main returning
	argv[0] in dli_fname field.

2000-11-15  Jakub Jelinek  <jakub@redhat.com>

	* Makeconfig (run-program-prefix): Move test-static test into the
	variable.

	* sysdeps/alpha/dl-machine.h (RTLD_START): Update _dl_argv.
	* sysdeps/sparc/sparc32/dl-machine.h (RTLD_START): Likewise,
	schedule instructions.
	* sysdeps/sparc/sparc64/dl-machine.h (RTLD_START): Likewise,
	schedule instructions, fix a bug in copying auxiliary data.

	* manual/startup.texi (Program Arguments): Fix type of main's envp
	parameter.
