I tried building ethereal with it, but it appears that at least one, if
not both, of libpcap and the packet library are linked with libcmt,
the multi-threaded version of the C support library, which means that:

	the standard Ethereal link causes complaints about "__tolower",
	or something such as that, being redefined;

	if I put in "/NODEFAULTLIB:libc", as I infer the linker is
	suggesting I should do, I instead get complaints about "_errno"
	not being defined.

Is it possible to build non-multi-threaded programs with winpcap?

If not, is it possible to build a non-multi-threaded program as if it
were multi-threaded (which Ethereal isn't) and have it still use
"errno"?  (Ethereal, not being multithreaded, doesn't care that "errno"
won't work right in a multithreaded environment if implemented just as a
global variable.)

If not, then it appears Ethereal can't use the current version of winpcap.
