Defaults to the first program found out of: `bison -y', `byacc', `yacc'. YFLAGS The list of arguments that will be passed by default to $YACC. This script will default YFLAGS to the empty string to avoid a default value of `-d' given by some make applications. LT_SYS_LIBRARY_PATH User-defined run-time library search path. PYTHON_VERSION The installed Python version to use, for example '2.3'. This string will be appended to the Python interpreter canonical name.
