[Mono-devel-list] "precise location handling" patch for mcs

[Atsushi Eno]

Hello,

... and with the latest patch here, I mostly reduced improper
lexer.Location.

But I made several changes and the patch went worse :(
The patch size doubled (60k->120k),memory consumption became larger
(53M -> 59M for building mcs; details are below), and it still does
not handle precise location for stack traces.

I'll improve this patch as long as possible.
