Objective Caml 1.05:
--------------------
* Typing: fixed several bugs causing spurious type errors.
* Native-code compiler: fixed instruction selection bug causing GC to
see ill-formed pointers; fixed callbacks to support invocation from a
main program in C.
* Standard library: fixed String.lowercase; Weak now resists integers.
* Toplevel: multiple phrases without intermediate ";;" now really supported;
fixed value printing problems where the wrong printer was selected.
* Debugger: fixed printing problem with local references; revised
handling of checkpoints; fixed problem with chop_extension.
* Macintosh port: fixed signed division problem in bytecomp/emitcode.ml
Objective Caml 1.04:

* The GNU C compiler gcc is recommended, as the bytecode
interpreter takes advantage of gcc-specific features to enhance
performance. Versions 2.5.8, 2.6.3, 2.7.0 and 2.7.2 have all been
tested at some point and appear to work.

at least under Linux; use some other version.
* Under HP/UX, gcc, the GNU binutils, and GNU make are all required.
The native cc, as, and make have major problems.

environment variable, or set it to /bin/sh.
* gcc 2.7.2.1 generates incorrect code for the runtime system in -O mode,
at least on the Intel x86 architecture; other processors have not been
tested with gcc 2.7.2.1. The solution is to downgrade to 2.7.2, or
upgrade to 2.7.2.2; both work all right.
* gcc 2.6.0 has been reported to generate incorrect code for the
runtime system in -O mode. Upgrade to a newer version.
