My OCaml patch to generate native code for 64 bit SPARC
systems now supports 64 bit Linux as well as Solaris.

This April 21 version also fixes a bug in the 64 bit
version of the caml_callback_exn internal function
which made user-installed signal handlers unreliable
in the April 9 version.

Read the README file or run the install.sh script
from the parent directory of the ocaml-3.08.3 source.
The configure script will select 32 or 64 bit code
to match the C compiler, so a typical configure
command for 64 bit code would be:
	./configure -cc 'gcc -m64'

Thanks to David Mentre for giving me access to a
SPARC/Linux system for testing.
