Changes:
improve hash function by using FNV-1 algorithm (patch/discussion by
Jim Mellander). This greatly improves speed for accessing arrays
with a large number of distinct keys; however the unsorted order in
"for" loops will differ.
add "internal regex" or "external regex" string to version message
to allow scripting based on support for embedded nulls.
drop obsolete CF_MAWK_PROG_GCC and CF_MAWK_PROG_YACC macros from
configure script (report by Mike Frysinger).
fixes to allow build outside source-tree (report by Mike Frysinger).
correct logic in scan.c to handle expression "[[]" (report by
Aleksey Cheusov).
add MAWK_LONG_OPTIONS feature to allow mawk to ignore long options
which are not implemented.
two changes for embedded nulls, allows FS to be either a null or
contain a character class with null, e.g., '\000' or '[ \000]':
+ modify built-in regular expression functions to accept embedded
nulls.
+ modify input reader FINgets() to accept embedded nulls in data
read from files. Data read from standard input is line-buffered,
and is still null-terminated.
update config.guess and config.sub
