+This file must be translated to C and modified to build everywhere.

+Run flex like this:
+
+  flex --prefix=cmCommandArgument_yy --header-file=cmCommandArgumentLexer.h -ocmCommandArgumentLexer.cxx cmCommandArgumentLexer.in.l
+
+Modify cmCommandArgumentLexer.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 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)
