0001-0004 seem pretty straightforward.
0005:
{realfail1} {
- /*

- * remains is an {integer} or {decimal}.
- */
- yyless(yyleng - 1);
SET_YYLLOC();
- return process_integer_literal(yytext, yylval);
+ yyerror("trailing junk after numeric literal");
}
realfail1 has been subsumed by integer_junk and decimal_junk, so that
pattern can be removed.
<SQL>{
+/*

It seems Flex doesn't like C comments after the "%%", so this stanza
was indented in 0006. If these are to be committed separately, that
fix should happen here.
0006:
Minor nit -- the s/decimal/numeric/ change doesn't seem to have any
notational advantage, but it's not worse, either.
0007:
I've attached an addendum to restore the no-backtrack property.
Will the underscore syntax need treatment in the input routines as well?
