Gambit-C 4.0 beta 19 is now available.  The source tarball is here:

     http://www.iro.umontreal.ca/~gambit/download/gambit/4.0/source/ 
gambc-4.0b19.tar.gz

A prebuilt installation for Microsoft Windows is available here:

     http://www.iro.umontreal.ca/~gambit/download/gambit/4.0/prebuilt/ 
gambc-4.0b19-win.zip

Just unzip it in C: to get C:\Gambit-C\4.0b19,
then add C:\Gambit-C\4.0b19\bin to your path.

Here are the highlights of this release:

    - The compiler incorrectly transformed (and X Y) when Y was a
      non-boolean constant.  This has been fixed.

    - The runtime system contained C++ style comments.  This
      caused problems on finicky C compilers (such as xlC on AIX).
      The comments have been replaced by C style comments.

    - Some changes were applied to gambit.h to support the ARM
      processor.

    - The predefined procedures "finite?", "infinite?", and
      "nan?" are now implemented.

    - The fixnum specific procedures "fxbitcount", "fxlength",
      and "fxfirst-bit-set" now conform to the R6RS draft.

    - Miscellaneous bug fixes.
