MSYS' automatic path conversion causes problems when passing paths as
defines ('-D' arguments to the compiler).  MSYS tries to be smart and
converts absolute paths to native Windows paths, e.g. if MSYS sees
"/bin" it converts it to "c:/msysgit/bin".  But we want completely
unmodified paths; e.g. if we set bindir in the Makefile to "/bin", the
define BINDIR shall expand to "/bin".  Conversion to absolute Windows
path will takes place later, during runtime.

I'll update the commit message.
