basic frontend / sdcc

Hi to all,
because now sdcc seems to usable as backend, i would place
to you'r attention the avBas compiler (i386 binary) compiler.
I would release the source after it's in beta state.
You can see it with a example from: http://m8-i.net/pic/avBas-alpha.zip
Currently, it's principally usable with the -I switch .

Because this is the first public outcoming, i would appredicate
any comment or feelings about the basic statements.

From the sdcc people, can you suggest me a better way to
optimize the high/low/output/toggle statements, if constants
are used and at the same time permit the usage of variables.
