+Run flex like this:
+
+ flex --prefix=cmCommandArgument_yy --header-file=cmCommandArgumentLexer.h -ocmCommandArgumentLexer.cxx cmCommandArgumentLexer.in.l
+
+Modify cmCommandArgumentLexer.cxx:
+ - add #include "cmStandardIncludes.h" to top of file
+ - put header block at top of file
+ - remove TABs
+ - remove "yyscanner" argument from these methods:
+ yy_fatal_error, cmCommandArgument_yyalloc, cmCommandArgument_yyrealloc, cmCommandArgument_yyfree
+ - remove all YY_BREAK lines occurring right after return statements
+ - change while ( 1 ) to for(;;)
+ - add "return 0;" to end of cmCommandArgument_yylex
+
+Modify cmCommandArgumentLexer.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)
