Writing Rules

[Rev. Jonathan T Sage]

Perhaps this is not the best place in which to ask this, If so, please point me
in the right direction.

I am working on adding some protability to a transparent IRC proxy, and have
encountered a situation where I need to know at compile time what version of
IPFilter is availible on the machine.  I have found this information, and I
have my code depnd on the definition of IPF_4_3 in config.h. What I don't know
is how to have autoconf take one and turn it into the other.

The information is in the header file /netinet/ipl.h, which I already test as
being there succesfully.  The version string is contained in that file at line
13 as :

#define IPL_VERSION = "IP Filter: v3.x.yy"

I need to define IPF_4_3 if x=4, and not define it if x=3.

Any help would be much appreciated

Thanks for your time ~Jon
