[xdebug-general] 1.3.1: debugclient compile failure

Hi there,

I had to make changes to main.c to get it to compile under FreeBSD 4.9
with the system libedit. The code is correct for FreeBSD 5.2 which
presumably has newer libedit imported. Could you please introduce some
checks into configure?

Or, I can produce something in exchange for a small README that says
how to actually use the client. :)
