From 4bed48398ff97b2d98cf4665b528a939c620522c Mon Sep 17 00:00:00 2001 From: Aaron Dierking Date: Thu, 14 Jun 2018 11:38:32 -0700 Subject: [PATCH] build: Detect Windows/MinGW at configure time Extend the host OS checks to define an OS_WINDOWS automake conditional if the host is MinGW-like. This will be useful for future Windows-specific build tweaks.
