	* catgets/catgets.c (catopen): Allocate sizeof(*result) bytes
	instead of sizeof(nl_catd) (which is just a pointer!).

Sat Sep  7 19:39:19 1996  Ulrich Drepper  <drepper@cygnus.com>

	* Makefile ($(objpfx)version-info.h): Generate from Banner files.
	* version.c (banner): Add contents of version-info.h to string.

	* Makerules: If $($(subdir)-version) is available name versioned
	shared library according to this value instead of glibc's version.

	* libio/Banner: New file.

	* elf/eval.c (funcall): Write error message in case function is
	not found.
	(eval): Recognize `_' in names.
