From f051e1b0af460483f8296f1e0a3c67fab073c448 Mon Sep 17 00:00:00 2001 From: Steve Chamberlain Date: Wed, 11 Oct 1995 20:40:45 +0000 Subject: [PATCH] Wed Oct 11 13:36:13 1995 steve chamberlain * dlltool.c (mtable): HOW_ALIGN_LONG, new. (d_ord): Deleted. (d_low_ord, d_high_ord, d_named_funcs): New. (gen_exp_file): Create noname entries correctly. (gen_lib_file): Dump exports alphabetically.
