You asked for a GCC front-end for Scheme.  That by definition means
"preliminary compilation before run" - that's what GCC does.

Now you're asking for being able "to compile function in a run-time
up to native code."  That's a completely unrelated problem with a
different set of issues.  I can think of two solutions if using
Kawa:
* Kawa (I don't know about Bigloo) will compile to bytecode at run-time.
A modern Java VM will Just-in-Time (JIT) compile the bytecode the native
code in-time fly.
* You can compile the bytecode, save them in a file, invoke Gcj to
create a DLL, and load that at run-time.  At least in theory and with
a little bit of work - I don't know if anyone has done it.

Because your question doesn't make sense.  RTL and Tree are data
structures internal to the GCC compiler.  They are not designed
for anything else.
