Run bison like this:

|
|
bison --yacc --name-prefix=cmExpr_yy --defines=cmExprParserTokens.h -ocmExprParser.cxx cmExprParser.y
|
|
|
|
Modify cmExprParser.cxx:
|
|
- remove TABs
|
|
- remove use of the 'register' storage class specifier
|
|
- add __HP_aCC to the #if test for yyerrorlab warning suppression
