Advice needed, please

[xelanoimis]

Hello,

I'm updating my scripting language and I need some help from someone more
experienced with bison who would like to have a look at my grammar. As it is
now it works fine, but I just want to make sure I didn't do any bad things
in there. Or if there's a way to "optimize" it, make the result smaller,
faster, etc...

Here are the links for the flex and bison files:

http://www.simion.co.uk/tmp/gslexer.l
http://www.simion.co.uk/tmp/gsparser.y

I have some "shift/reduce conflicts" and I wonder if I must fix them or just
use the %expect option to silence the warning.

Also I wonder about reporting the parser error. I get the line number but it
doesn't always say a suggestive message, like missing ';' or missing '}'.
For example when I have an error in the top level it says: "parse error,
expecting '$". I'm not sure where this came from and how can I get a better
message.

Any help is greatly appreciated.
Thanks a lot!
Alex
