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 The comments have been replaced by C style comments.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.
