This file must be translated to C and modified to build everywhere.
Run bison like this:
bison --yacc --name-prefix=cmDependsFortran_yy
--defines=cmDependsFortranParserTokens.h
-ocmDependsFortranParser.cxx
cmDependsFortranParser.y
Modify cmDependsFortranParser.cxx:
- remove TABs
- remove use of the 'register' storage class specifier
- Remove the yyerrorlab block in range ["goto yyerrlab1", "yyerrlab1:"]
