guile-1.6.3 port

[gwright@…]

A port of the guile scheme interpreter, version 1.6.3. On OS X 10.2.4 it passes all tests, with 2 'unresolved' warnings from a garbage collection test.

The tests giving the warnings check whether a structure allocated and immediately unreferenced is collected on the next GC pass. According to a couple of threads on the guile-devel mailing list, this is an expected behavior of the conservative garbage collector. (If the C stack is tickled by other activity the GC may not find unreferenced objects on the first pass.) Modifying the test to do a second GC pass results in success. The same behavior is seen on the Alpha. Noted in the interest of full disclosure, but probably not an issue.

Committed to lang/guile - thanks! This was a very well-made port and downright trivial to commit on your behalf (usually we have to fix 'em first). The quality control work up-front, both on the port and this bugzilla entry, is highly appreciated!
