[Samba] Samba 3.0.20a on AIX 5.2

[Ric Tibbetts]

While I was between other things, I thought I'd try to build this.
The build failed with:

Compiling dynconfig.c
In file included from include/includes.h:507,
                  from dynconfig.c:21:
/usr/include/aio.h:76: field `aio_sigevent' has incomplete type
/usr/include/aio.h:127: field `aio_sigevent' has incomplete type
In file included from dynconfig.c:21:
include/includes.h:811: redefinition of `struct timespec'
make: 1254-004 The error code from the last command is 1.

Same problem as 3.0.20
