From: Simon Marchi Date: Wed, 15 Jul 2020 16:17:24 +0000 (-0400) Subject: configure: enable -Wstrict-prototypes unconditionally X-Git-Url: http://git.efficios.com/?p=babeltrace.git;a=commitdiff_plain;h=6567934701fb3446f1ef943aaa8f24844c81bfdc configure: enable -Wstrict-prototypes unconditionally I noticed that -Wstrict-prototypes would not get enabled, because the autoconf test program generates a warning of this type. Enable it unconditionally, like we already do for -Wold-style-definition.
