From 07c2f075fc06014700d6bea35c634fc5e1ca09ce Mon Sep 17 00:00:00 2001 From: "Frank Ch. Eigler" Date: Mon, 4 Oct 2004 17:33:54 +0000 Subject: configure.ac: Look for more headers & functions. 2004-10-04 Frank Ch. Eigler * configure.ac: Look for more headers & functions. * mf-hooks2.c (getmntent, inet_ntoa, getproto*): New wrapper functions. * mf-runtime.h.in: Add new "#pragma redefine_extname"s for them. * mf-runtime.c (options): Clean up integer signedness warnings. (main): Add a declaration to fix a warning. * mf-hooks3.c (pthread_exit): Add not-reached exit() to wrapper. * configure, config.h.in: Regenerated.
