Removed the incorrect reference to caml_aligned_malloc

I'm not completely sure, but I don't think that the fix for this is to move the #define outside a CAML_INTERNALS block.

There is a discussion in the GPR about the removal of caml_strdup - skimming through it, it's possible that what should change is documentation to show that we removed caml_strdup and that code should be *updated* to use caml_stat_strdup (with any corresponding free call changed to caml_stat_free). Max's analysis of opam seemed to suggest that correct usage of caml_strdup which very limited.

dra, let's move on with the plan of properly documenting the breakage (first, is "caml_strdup" present in a star-marked Changes entry ? If not, maybe we could create one pointing at GPR#71, or at least add it to the GPR's existing entry). Would you be able to submit a PR for this shortly?

I'm not sure that was the original intention of GPR#71, though?

Ok, so I pinged Max in the PR.

Putting those aliases into CAML_INTERNALS was not intentional, and is likely an artefact of a sloppy rebase. There should be no breakage in the client code, unless the runtime is started with caml_startup_pooled (which requires that caml_stat_* blocks are only disposed with caml_stat_free).

Fix: [^]
