C99 stdint.h is provided by VS 2010 and later. GLFW has not provided testing or binaries for VS 2008 for several releases. For earlier versions of VS there are third-party alternatives: https://msinttypes.googlecode.com/svn/trunk/stdint.h http://www.azillionmonkeys.com/qed/pstdint.h This change does not affect the ABI.
