Hi,

since 3.08 global C identifiers are prefixed with "caml_" to
avoid name clashes with other libraries. However, this applies
only to function names and not to type names. Therefore it for
instance not possible to use the CAMLlocal macros in a method of
a class that declares a value field: one will get a clash with
the value type used inside CAMLlocal.

"value" seems to be a very common identifier and should be
renamed. But also the other publically visible types and macros
in mlvalues should get some caml prefix.

Bye,

Hendrik
