The problem is actually that we don't have nice `plug-n-play' patches
for rpc2 decoding. Our current setup depends on the protocol opcodes
(i.e. headers) generated by rp2gen, and the resulting tcpdump can only
pretty-print Coda traffic.

Ok, I've applied your patch, actually testing ${prefix} first. I don't
think we need CFLAGS during the test at all. We are only attempting to

    int main(void) { return 0; }

against -L${path} -llwp. If a path is found, then we set CFLAGS and
LDFLAGS at some later point.

Yes, at some point I'd like to move the main coda tree to automake as
well. I already got rvm and rpc2 separated, still cleaning the build a
bit, your patch has been applied to them as well. This way all the
libraries that I care most about becoming shared libraries, and needing
libtool, are then external packages.

Also, RVM and RPC2 are relatively difficult to `automake'. RVM compiles
the same source tree with different options, once for libxxx and once
for libxxxlwp. RPC2 is difficult to cross-compile, it needs to build
rp2gen for the native environment. So separating these was a good
exercise for me to learn how to use automake :)

Nice, it looks like we got this working well on all platforms by now.

If people would like to test whether rvm and rpc2 build correctly on
different platforms. They are in the CVS repository as `rvm' and `rpc2'.
