src/snprintf.[ch]:
	Added Mark Martinec's replacement (v)snprintf from
	http://www.ijs.si/software/snprintf/ for systems without (v)snprintf
        (or with a broken one)

src/compat.c:
	Renamed inet_aton to libopm_inet_aton to avoid clashes.

src/compat.h:
	On systems without inet_aton, use libopm_inet_aton.

	On systems without (or with broken) (v)snprintf, use
	libopm_snprintf (from snprintf.c).

	On systems without inet_pton, use libopm_inetpton (from inet.c).

src/inet.c:
	For now made inetntoa() static, as it is used nowhere else but
	this file.

	Commented out inetntop() -- it doesn't seem to be used anywhere?

	Removed bopm_gethostbyname() -- it wasn't used anywhere.

src/proxy.c:
	No longer needs to include stdio.h.

src/test.c:
	Needs to include compat.h and be linked with compat.o.
