config.h is only used on Unix, so only Unix builds need to include it.  
Things like HAVE_LIBPCAP are defined in there according to the configure 
script's results, which various Wireshark source files can use to 
include/exclude code specific to certain optional features such as 
libpcap or adns/libsmi/c-ares/etc.
