From 164a5e3faab931a6c6459b56acae7f91dde6337d Mon Sep 17 00:00:00 2001 From: Marius Storm-Olsen Date: Wed, 16 Sep 2009 10:20:28 +0200 Subject: Add MSVC to Makefile Enable MSVC builds with GNU Make by simply calling make MSVC=1 (Debug build possible by adding DEBUG=1 as well) Two scripts, clink.pl and lib.pl, are used to convert certain GCC specific command line options into something MSVC understands. By building for MSVC with GNU Make, we can ensure that the MSVC port always follows the latest code, and does not lag behind due to unmaintained NMake Makefile or IDE projects.
