47: # RELEASE - Create a release build #
48: # (Mutually exclusive, if both are set, RELEASE #
49: # is cleared) #
50: # DONT_CLOBBER_CC - Do not change the default setting of CC #

77: # LIB_LDFLAGS - Libraries appropriate for link command-line usage #
78: # COMPILE_MSG - Message saying a target is being compiled #
79: # DIRSEP - The directory seperator this system likes most #
80: # VERSION - Synchronet version number in MAJOR.MINOR format #
81: # (Numeric ONLY) #
82: # OUTPUT - Compiler flag specifying output filename #
83: # LOUTPUT - Linker flag specifying output filename #
