Indeed, the current configure.in has a number of issues.
They are related to :
	- libusb detection
	- libneon detection
	- linking to regex
	- duplication of DATADIR macro
	- definition of socklen_t
	- inet_aton detection

Arnaud is currently working on all this.

The way I use to build the project is by commenting out faulty macros in
configure.in and adding LIBS=-lregex to the configure command line (and
--without-serial too, because those drivers has not been ported yet).
Not the clean way but it is just a temporary workaround while waiting
for Arnaud's commit.

Fred
