Of the eleven cygwin flex v2.5.35 generated .c files:
All but one have the unistd error.
All but one have the 'not enough actual parameters' warning.
Six of the files have a 'signed/unsigned mismatch' warning.
1. re: unistd:
I'll see if I can gin something up for the config.nmake which
automatically determines if --nounistd is supported by the
version of flex being used.
2. re: 'wrap' related warning:
I'm now inclined to just remove the '%option noyywrap' and to add
the int xxx_wrap(void) { return 1;} to each of the files (as
you originally suggested). (This is what is already being done
in text2pcap-scanner.l).
(It would be possible to have runlex.sh add the #pragma warning(...)
to the generated xxx_lex.h file, but I think the above is better).
3. re: signed/unsigned mismatch:
I'll have to track these down...
I'll work on this tomorrow (Thurs).
Note: FWIW: For the one case I checked the unix flex generated .c file was
about the same as the file generated by cygwin flex v2.5.35 ....
