From a64e37a1d3990b9c2524d166119cb5564dc5d96c Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Tue, 12 Apr 2011 11:43:11 -0700 Subject: configure: Add option --enable-Werror to add -Werror to CFLAGS. -Werror is useful for development, but it screws up configure because it's impossible to guess what new warnings compilers will add in the future. This commit adds a new configure option to add CFLAGS after the configure checks are done. The use of AC_CONFIG_COMMANDS_PRE is based on Eric Blake's suggestion on the autoconf mailing list: "AC_CONFIG_COMMANDS_PRE probably fits the bill as the ideal macro to use for guaranteeing that you inject your shell code at the last possible moment."
