Hi Alex,
Thank you for the clarifications.
In case you are having issues with GAS, you may want to look at YASM
<http://www.tortall.net/projects/yasm/wiki> from what I can see it's
under active development and the source looks reasonably clean.
Cheers,

It would appear that you could claim portability to any CPU. Afterall,
porting should only require writing a translator module for the

be what needs rewriting.
Yes, this would be an interesting exercise.
As for the gcc.l, as.l, and the generic call to external libraries, I
have a suggestion:

I'm thinking of something similar. Not with a separate manifest file,
but with some encoding conventions in an s-expression, specifying the
types and layouts of arguments and return values.
This would allow to call almost any C function in an external library on
the fly. The calling mechanism itself would be the same as it is in
picoLisp-2.x, just with some glue functionality interpreting the encoded
information, and preparing the arguments and return values
appropriately.
A slight disadvantage compared to your proposal is some runtime
overhead, though. Let's see ...
