Re: yy_current_state, stuff

[Jordan DeLong]

start conditions are a bit different than states.  I want to be able to 
interrupt the
scanner in the middle of scanning and be able to resume without problems.  Such 
as this:
the scanner has read the letters 'i' and then 'n' while in the INITIAL start 
condition, and
then is interrupted, when it comes back to the scanner, in order for it to know 
that the
't' char it reads next makes it complete the rule for <INITIAL>"int" it needs 
to have the
yy_current_state variable (declared in the yylex func) restored (in addition to 
the start
condition vars, etc.)
