Subject: (svn r7759) -Merge: makefile rewrite. This merge features:  - A
 proper ./configure, so everything needs to be configured only once, not for
 every make.  - Usage of makedepend when available. This greatly reduces the
 time needed for generating the dependencies.  - A generator for all project
 files. There is a single file with sources, which is used to generate
 Makefiles and the project files for MSVC.  - Proper support for OSX universal
 binaries.  - Object files for non-MSVC compiles are also placed in separate
 directories, making is faster to switch between debug and release compiles
 and it does not touch the directory with the source files.  - Functionality
 to make a bundle of all needed files for for example a nightly or
 distribution of a binary with all needed GRFs and language files.

Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy.
