Much improved error reporting when a library is not found.
...
Example:
> (import (a b c))
Unhandled exception
Condition components:
1. &error
2. &who: expander
3. &message: "cannot locate library in library-path"
4. &library-resolution:
library: (a b c)
files: ("./a/b/c.ss" "/Users/ikarus/.opt/lib/ikarus/a/b/c.ss")

Fixes bug 163589: ikarus does not support the #!r6rs comment.
...
* Added #!r6rs and #!ikarus tokens to the reader
* #!r6rs disables the #:foo and #{foo bar} gensym syntaxes and it
also disables the #n= and #n# graphs marks syntax.
* #!ikarus enables both options.
* every opened port starts in the ikarus-mode by default.
2007-11-18 19:53:32 -05:00

* The fasl loader has reduced the startup mmap frenzy for code
...
objects from 5242 pages (almost one page per code object) down
to 785 pages. Special thanks to Michael Adams for counting the
the number of pages that were used and touched at startup; without
his help, I wouldn't have optimized it in about 10 minutes of
coding time.
