void cimmof_yy_less(int n) { yyless(n); }

// Implemented to hide bison functions that are defined but not used

// so compiler unused warnings can be enabled. The functions defined in ths

// dummy function are those current defined by Flex but never called by

// Pegasus lex definitions. Since each compiler has different rules for

// hiding unused functions, we implement each that we know.

// CLANG can use the pragma below.

// GCC hides the unused function through the recursive call

// NOT tested with other compilers.
