C macro name clash in Ocaml 3.00 source

[STARYNKEVITCH Basile <Basile.Starynkevitch@cea.fr>]

Hello All (and particularily Ocaml developpers),

There are some annoying name clashes in Ocaml public includes
<caml/mlvalues.h> and <caml/misc.h> 

As an example, Atom is a a unary macro in <caml/mlvalues.h> and is
also a type in <X11/X.h>. Also Assert is quite easily used by (other)
applications. etc...

I suggest that all publicly visible macros (i.e. those defined by
<caml/*.h> file included by an application C wrapping code) would have
a common prefix. Therefore Atom in <caml/mlvalues.h> would become
OCAML_Atom, Assert would become OCAML_Assert, etc... and so forth.

I may even volonteer for this boring job (it wont take too much of my
time since I do know quite well the Ocaml implementation) if I am sure
that my patches would be included in the next Ocaml release.

(Compatibility with old C source could be kept with optionaly #define-ing
Atom as OCAML_Atom etc....)

Regards.
