From b849e63fbfcddae7c770944816544c4799856042 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Sat, 29 May 2010 13:06:19 +0200 Subject: [PATCH] configure: make implicit declarations fatal from bugzilla #105: "ngircd-16 works great under openbsd4.7/i386, but it segfaults on openbsd4.7/amd64." Caused by missing function prototypes and the resulting truncation of pointer to int. Lets try to catch these bugs during compilation instead of SIGSEGV. --- configure.in | 1 + 1 file changed, 1 insertion(+) diff --git a/configure.in b/configure.in index 6d9312d4..8526af60 100644 --- a/configure.in +++ b/configure.in @@ -542,6 +542,7 @@ AC_DEFINE_UNQUOTED(TARGET_OS, "$target_os" ) # Add additional CFLAGS, eventually specified on the command line, but after # running this configure script.
