A new beta of Gambit-C 4.0 is now available in source form at this address:
http://www.iro.umontreal.ca/~feeley/gambc4b10.tar.gz
Here are the main changes:
- all homogeneous vector primitives (u32vector, etc) should now work properly
- fixed a few "configure" problems on Mac OS X and Solaris
- should build without problems on 64 bit machines (I have only checked on a SUN Ultra-sparc, so if you have access to a 64 bit machine, please report on your success)
- interpreter handles procedure calls of up to 4 arguments faster than the general case (5 and more)
- implementation of (vector 1 2 3 4) has been improved
- I now include the portable "syntax-case" implementation that has been ported to version 4.0 of the Gambit-C interpreter (it is in misc/syntax-case.scm). To use it start gsi like this:
gsi misc/syntax-case.scm -
You can also rename the file to gambcext.scm and move it to the Gambit installation directory (and even compile it with "gsc -dynamic gambcext.scm" if you wish to speedup macro expansion).
Unfortunately, if you use this package all source-code location is lost and debugging will be more difficult.

Is there also a syntax-case implementation for the Gambit-C compiler somewhere?

You can add this line to misc/syntax-case.scm:
(define c#wrap-program (lambda (src) (c#expression->source (expand-syntax (##desourcify src)) src)))
If you want to be able to use this with gsc's batch mode, then you should rename syntax-case.scm to gambcext.scm and put that file in the Gambit installation directory. But be aware that source code location tracking will not work. This is why syntax-case.scm is not built into the system by default (if someone can make a clean port of syntax-case to Gambit I'll gladly make it a built-in feature!).
