Sat Sep 7 14:00:33 1996 David Mosberger-Tang <davidm@azstarnet.com> * 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.
