I just updated from CVS and rebuild FPC, and indeed, timings of my test 
program are now
   Time of Foo_ResourceString:        18
   Time of Foo_ResourceString_Faster: 16
So it's fixed in compiler. Great!

Are there any other cases where this issue may be significant ? If no, 
I'll mark this wiki page clearly as "only for FPC earlier than 
2004-12-28" (to-be-removed when 2.0 comes in), else I will update it.

(Note: we can continue this talk on wiki page
http://www.freepascal.org/wiki/index.php/Talk:Avoiding_implicit_try_finally_section
already started by Vincent with that question)

Thanks!
