Charles, I know your plate is full, but came across this and thought I would put the link up while I had it.
It is for using gcc to compile for Arm based devices. This way O2 can be cross platform in the future.
http://www.gnuarm.com/
I came to that link from this article and links.

Yes emitting GCC source is probably the easiest way to develop software for these ARM based devices. There will be a variety of architectures (cores and ?video devices) to deal with, so you can't go in at a low level without specialising.

FreeBasic has also added an GCC emitter into the code (still in the works).
The ingenious thing in their approach is to use gcc as a low level compiler without using C header files (some header files could be missing in some gcc installations - different header files on Windows/Linux etc).
So the beginning of the emitted C file is full of typedefs in order to make it work.

O2 is already very close to C in terms of syntax comprehension so it won't be too much work to emit C source. But the runtime library will also have to be in C rather than Assembler as it is now. while I am beavering away on the RTL, I will explore how to do this efficiently - perhaps most of the work can be passed to the C run-time for memory management and string/float conversions.
This would take more a BCX translation approach rather than go for a C emulation of Assembler.

Charles,
You can't be everything to everyone. I think your current direction of a lighting fast, easy to use, JIT Basic compiler is more than anyone could ask for. The ability to use C .h files, dynamic and static link is more than most Basic projects could dream for. You have a big heart and you're a miracle worker. State your goals and milestones and allow for minor alterations along the way. It's really easy to get side track from a cool request a user may have.

I concur...

Exactly...
Charles, what is it with this GFX-Surfaces playing around anyhow?
Go back to work!
Just joking! ;D
Do whatever makes you happy!

I'm really thinking about mobile devices where the hardware architecture is likely to be so diverse or made deliberately opaque so it becomes infeasible to produce native code. I have been gradually weaving C syntax into the compiler architecture for some time. It has cost little in additional code but often requires rearranging procedures and careful testing - so it is a gradual process.
But I have not developed a semicolon spraying device yet :)

Embedded single quotes and tabs in data are my button. ;)

Thats good, I dislike the semicolon very much (except as a start of comment symbol...)
