the following type error
"Type a is not compatible with type 'a"
should contain the constraint on 'a.
"Type a is not compatible with type 'a = < .. >"
"Type a is not compatible with type 'a = [> `b]"
Some files were added with CRLF line-endings rather than normalised LF
line-endings which interferes with the .gitattributes file change made
in d8b7a4f48e
Only alteration is line-endings (i.e. git diff --ignore-space-at-eol
returns no differences)
This week we merged several changes from Thomas Refis, to allow the
use of exception patterns under or-patterns, to write code such as
match foo x with
| None | exception Not_found -> ...
| Some -> ...
Unfortunately, I failed to properly assess the impact of this change,
and in particular to make sure that Luc Maranget had properly reviewed
this code -- any change to the pattern-matching machinery should be
reviewed by Luc.
The problem that I had not foreseen and that he would have immediately
realized is that, while adapting the pattern-matching *compiler* is
relatively easy (Thomas inserted a transformation at the right place
to separate exception patterns from the others and handle them
separately, using the staticraise construct used by the
pattern-matching compiler to avoid duplicating the
right-hand-side branch), adapting the pattern-matching warnings
machinery is both more subtle and easier to overlook (it may fail
silently and nobody notices, unlike wrong code production). This part
of the compiler is subtle and best understood by Luc, but he does not
have the time to do a proper review of those changes in the timeframe
for the 4.03 feature freeze (mid-December).
I believe the right move in this case, implemented in the present
commit, is to revert the change from trunk (this is not a feature that
we must *imperatively* have in 4.03), do a proper job of understanding
the changes, and integrate the change when we are confident it is
ready. I hope to do this in 2016, together with Luc Maranget and
Thomas Refis -- hopefully this would allow Thomas and I to be more
confident when changing the pattern-matching machinery in the future.

There used to be a limitation to 32 binding groups, which is now lifted by dynamically allocating the groups data if it is too big.
Also:
- Modernize strstubs.c to use the Caml namespace
- Fixed a potential bug with backreferences \\n referring to a nonexistent group.
For each function there are two sets of tests, one on an empty and one on
an full set of elements. They use some simple predicates to test whether
for_all and exists work as expected.
