The gambc packages have entered Debian unstable. This version splits off the docs and the shared library. It has been configured with the --enable-single-host option for better performance. The b17 packages have been removed from Alioth; get your packages with apt-get.

The gambc package includes a Scheme interpreter and a Scheme compiler which can be used to build standalone executables. The thread system is very efficient and can support millions of concurrent processes.

The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme standards. The full numeric tower is implemented, including: infinite precision integers
(bignums), rationals, inexact reals (floating point numbers), and complex numbers. Gambit-C supports a number of extensions to the standards.
