success compiling NSCA on AIX 5.3 with gcc

[Vonnahme, Nathan]

It's been way more complicated and weird than I expected, but I got the
send_nsca client to compile on AIX 5.3

First I had to get the prereqs right:

- installed libmcrypt from source (http://mcrypt.sourceforge.net/)
	I had to hack the Makefile to remove '-1.7' in a few places for
some reason
- installed Berkley DB (db-3.3.11-4.aix5.1.ppc.rpm) from IBM's Toolbox
for Linux apps
(http://www-03.ibm.com/servers/aix/products/aixos/linux/download.html)
- installed tcp_wrappers installp package from
http://www.bullfreeware.com/

When I ran ./configure on AIX, the 'make' broke (see output below).  So
then, and this is the spooky part, I ran ./configure on a Linux machine
(RHEL4), and 'make send_nsca' then worked on my AIX machine:

$ make send_nsca
        cd ./src/; make send_nsca ; cd ..
        gcc -g -O2 -DHAVE_CONFIG_H -o send_nsca send_nsca.c netutils.c
utils.c  -lnsl

The binary appears to work fine.

I am ignorant about make/configure stuff, but I think the configure
script is based on really old AIXes and when it sees "aix" it thinks it
should complicate things a lot.  But AIX 5L is (deliberately) very
linux-like, especially when it comes to running gcc.  One of the goals
for AIX 5L was supposed to be "100% source compatibility with Linux"

Maybe someone who knows more about automake/autoconf could fix the
configure script?  I'm happy to test...
