From 320d060ae94eea9018ee4292cd18b506c333d377 Mon Sep 17 00:00:00 2001 From: Diego Biurrun Date: Mon, 30 Jan 2006 00:22:41 +0000 Subject: [PATCH] On MinGW it is not possible to build shared and static libraries at once. Add means to disable building the static libraries and fix a few issues with the MinGW build. All the hard work done by Alexander Strasser, minor changes by myself.
