------------------------------------------------------ The main porpouse of this file is to build linux gcc makefiles.-- Must have Premake version 3 installed.-- Original Premake was changed to remove some parameters and add others.-- Default parameters:--   premake3s --target gnu --os linux-- But it can build windows gcc makefiles, and visual studio projects.--   premake3s --target gnu --os windows--   premake3s --target gnu --os macosx--   premake3s --target vs6--   premake3s --target vs2002--   premake3s --target vs2003--   premake3s --target vs2005           (MUST UPDATE DEPENDENCIES)-- In Linux the generated makefiles will not correctly build libraries in 64-bits.--              must add "-m64 -fPIC" flags----------------------------------------------------if (not
