Hello

If anyone is facing the issue of not being able to locate unistd.h file in scanner.c file , just copy a blank unistd.h file in
C:\Program Files\Microsoft Visual Studio 8\VC\include\sys

Directory. No need of changing anything in the fparticular file as that file is being automatically generated in build process and everytime
You make distclean the same problem will be reproduced during the 
build process
 

Try searching the archives.  This has come up before.


Specifically: see Bug #2493 (especially Comment #15)

Unfortunately the latest cygwin version of flex causes some problems when building from Windows Wireshark 1.0 source.
You can either follow the suggestions in the above referenced comment or
download the latest development Wireshark SVN (which has a correction for this problem).
