+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, cmExpr_yyalloc, cmExpr_yyrealloc, cmExpr_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)
