 | "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.
 
 I thought that this is limited by NCHARS+3. I will change it.
 
 | 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?
 
 They were not done carefully so bugs were introduced and we decided
 to back them out until someone does them carefully.
 
 | P.P.S
 | Where is nawk upstream? Who maintains that YYYYMMDD versions?
