+[the following was already reported in November 2001 for Flex
+2.5.6-developer-2001-11-01, but the bug is still present in Flex 2.5.8]
+
+Just a little thing I've recognized while hacking on a scanner which is
+generated by flex-2.5.8: Although I used "flex ... -Pl2_spec_ ..." the
+generated object file still has two "yy"-prefixed symbols:
+
+| :> nm -g l2_spec_scan.o  | grep yy
+| 00000c04 T yyget_lloc
+| 00000c10 T yyset_lloc
+
+This is because at the top of the generated l2_spec_scan.c there is:
+
+| #ifdef YYLTYPE
+| #define yyget_lloc l2_spec_get_lloc
+| #define yyset_lloc l2_spec_set_lloc
+| #endif
+
+Unfortunately the YYLTYPE will _never_ be defined at this point, because
+it is defined by the parser and the parsers' include file can be included
+only in %{ ..%} sections, which in turn are inserted in the generated
+code always _after_ the above sequence.
+
+It certainly is not correct to change the position of inserting
+the %{...%} sections, of course. But we can just leave out the
+#ifdef..#endif, because even if YYLTYPE is not used (no location
+tracking is used) or not defined, the extra namespace-preserving
+definitions of yy[gs]et_lloc will not hurt.
+
+So, I recommend to apply the following patch to Flex 2.5.8 and hope it
+is finally considered for inclusion into forthcoming versions:
