I though PATH_MAX was a fairly standard definition, but it appears that
it is not defined everywhere. I'll add a check for this to the configure
script, and make sure it gets defined if there is no standard definition
available for it. Try the attached patch (run a "make clean" before
re-building the client).

The native cc command on this platform appears not to support the C99 
standard. Hobbit uses the "long long" datatype for a few things; this 
is standard in C99 which gcc supports. So I'd recommend using that.
