[BUGFIX][PATCH 0/1] Enable 4.4 to build on CentOS/RHEL 5.10

[Don Slutz <dslutz@verizon.com>]

I only did Andrew Cooper's statement of "Applying the top macro".
There is no checking of ocaml version.

Since CentOS/RHEL 5.10 (Released on 22-Oct-2013) disto provides
ocaml 3.09.3, the current code does not build.

Compile tested and simple tests done on CentOS 5.10 and Fedora 17.

Note: The formating of the code was changed to be closer to "Coding
Style for the Xen Hypervisor".  The file has a non-standard emacs
setting at the end (indent of 8 and use tabs).  And the example of
code just below was not used as an example of coding style to
follow do to lack of indent at all.

I feel this should have a release exception and go into 4.4 for 2
reasons:

1) It is a bufix for CentOS/RHEL 5.10 and looks to be low risk.

2) It make the release more awesome to run on these distros.


"What functionality is being fixed / enabled by this patch?"

4.4 Added CAML_returnT usage.  ocaml provided this at 3.09.4.


"If there was a bug in this patch, what functionality might be broken?"

ocaml may stop functioning.  Since this is conditional code, ocaml
should only possibly have issues on CentOS/RHEL 5.10.


"What is the probability that this patch has a bug?"

I feel it is low.
