#   Description
#
#	This is a GNU Makefile that uses GNU compilers, linkers and cpp. The
#	platform specific issues are determined by the various OS teets that
#	rely on the uname(1) command and directory locations.
#
#	Set additional flags for the build with variables CFLAGS_USER,
#	DEFS_USER and LDFLAGS_USER.
