[erlang-patches] Erlang on AIX 5.3

[VAUCHER Laurent]

  Hi.

  I'm trying to compile R11B2 on AIX 5.3 and, as you might guess, it
fails.
I can help fixing it, but I will need some help.

First, the ./configure script warns me that odbc will not be built
(that's probably normal).
Then, when doing make, compilation fails on
erts/emulator/sys/unix/erl_check_io.c
The problem comes from AIX, in fact, because the included <poll.h> file
does a very nasty trick: it simply #defines events and revents. And
those identifiers are used as struct fields in
erts/emulator/beam/erl_driver.h
Well, I have found a kind of workaround, which is to force #include
<poll.h> just before the struct definition. I have not yet found how to
protect this include so that it only happens on AIX.

Compilation seems to proceed further, but then

=== Entering application parsetools

Examine file headers with the 'dump -ohv' command.

  I have no idea what this can mean. The suggested dump -ohv on 'beam'
gives the folowwing result

  Does anyone have an idea here?
