/*
This file must be translated to C and modified to build everywhere.
Run flex like this:
flex --prefix=cmExpr_yy --header-file=cmExprLexer.h -ocmExprLexer.cxx cmExprLexer.in.l
Modify cmExprLexer.cxx:
- remove TABs
- remove "yyscanner" argument from these methods:
yy_fatal_error, yyalloc, yyrealloc, yyfree
- remove all YY_BREAK lines occurring right after return statements
- change while ( 1 ) to for(;;)
Modify cmExprLexer.h:
- remove TABs
- remove the yy_init_globals function
- remove the block that includes unistd.h
- remove #line directives (avoids bogus warning on old Sun)
