Note that we now attempt to work around AIX BPF's weirdness, indicate
that there may be compile-time or run-time problems with the workarounds, suggest that people send in a detailed report and fall back on DLPI if they have those problems, and suggest that if they construct fixes for the problems they send them to patches@tcpdump.org. Fix the white space.

-(1) To configure libpcap under AIX 4.x, you should use DLPI instead
- of BPF, since IBM's version of BPF includes some undocumented
- and unsupported changes to the original BPF.
+(1) AIX 4.x's version of BPF is undocumented and somewhat unstandard; the
+ current BPF support code includes changes that should work around
+ that, but, lacking an AIX machine on which to compile it, we don't
+ know whether the BPF support for AIX will compile.
+
+ If it doesn't, or if the workarounds fail to make it work correctly,
+ you should send to tcpdump-workers@tcpdump.org a detailed bug report
+ (if the compile fails, send us the compile error messages; if it
+ compiles but fails to work correctly, send us as detailed as
+ possible a description of the symptoms, including indications of the
+ network link-layer type being wrong or time stamps being wrong).

+ If you fix the problems yourself, please send to patches@tcpdump.org
+ a patch, so we can incorporate them into the next release.
