newlib "light!

I am developing communications applications on a 68LC302 platform using
the gcc toolchain and newlib. I've seen the binaries are much bigger as
the same application generated with a commercial toolchain. This is not
a compiler but a newlib issue. The commercial library does not have
floating point support, which is not needed in my application. (They
have a floating point version too).

My question: Is it possible to strip down newlib to a  pure integer
version (printf etc.)? A short look into the sources showed some
#defines which may imply that it is possible, but I could not find
options to configure it. The newlib sources are a real jungle for me.

Is there any documentation available how to tailor newlib?

Thanks in advance
