Unlimited objects patch from Chris Johns <ccj@acm.org>. Email follows:
First, the unlimited patch. I have compiled the unlmited patch for the
Linux posix BSP only and it seems to work cleanly. I would like a really
major application run on this change before commiting as the changes are
very core and significant. I am currently building all the tests to run.
I have no targets suitable to test on at the moment.
I have tested the patch for inline functions and macros.
Turning macros on has found some core bugs. I have fixed these but have
not run all the tests. Please review the patch for these changes. They
are:
1) The conditional compilation for MP support broke the core messages
code. You cannot embed a conditional macro in another macro. The Send
and Urgent Send calls are macros.
2) User extensions handler initialisation now has two parameters. I have
updated the macros to support the extra parameter.
The patch also contains the gcc-target-default.cfg fix required to build
the kernel. More of a by product than a fix for you.
