"640k is anough for everyone" ;)
Seriuosly, I often use awk with very large regexps for my work.
AFAIR, according to theory NFA for regexp
that looks like (a|b)*(a|b)^n has equivalent DFA with 2^N states, so 65536
states of DFA may correspond to NFA with only 16 (!!!) terminal
symbols.  IMHO this kind of internal limits is bad. I read
NetBSD philosophy but reality is that hardware changes fast.
My 5 years old Athlon-800/384Mb RAM is capable of propressing
DFAs including more than 2^16 states.
So, I personally would prefer 'int' type for the states.

P.S.
I saw HEAD changes in awk code and was surprized that
lots of snprintf functions was changed to sprintf,
and strlcpy to strcpy. Is this really ok?

P.P.S
Where is nawk upstream? Who maintains that YYYYMMDD versions?
