[syslog-ng]1.6rc2 build problem

[Brian C. Hill]

	I had the exact same problem when building 1.6rcX with a 64-bit
capable gcc 3.2.1, but forcing it to a 32-bit compile with -m32. I had
to 'hide' flex so that configure couldn't find it (not for libol - I am
pretty sure just for syslog) and allow it to use lex
(/usr/ccs/bin/lex). When I built it in 64-bit mode, I didn't have the
flex problem (didn't have to hide it), but syslog 1.X have a particular
type casting defficiency that prevents it from properly recording the
srouce address.  I have patch for that, but I haven't tried it yet. I
am running it in 32-bit mode.

Hope that helps.
