Details:

Reader macros used in our (Merced Systems) source are no longer working with
the latest Kawa sources.



I've attached a small patch that demonstrates the problem.  Here's what I'm
getting now:



% make NEW=1 default

rm -f *.class

CLASSPATH=.:~/kawa/cvs/kawa-pure-build/kawa-1.7.91.jar java kawa.repl
--warn-undefined-variable --main -C reader1.scm

(compiling reader1.scm)

CLASSPATH=.:~/kawa/cvs/kawa-pure-build/kawa-1.7.91.jar java kawa.repl
--warn-undefined-variable --main -C reader2.scm

(compiling reader2.scm)

(set-dispatch-macro-character ...) called, I think.

reader2.scm:5:1: let has no value for 'a'

reader2.scm:5:12: invalid dispatch character '@'

make: *** [reader2.class] Error 255



and here's what I get with a previous version of Kawa:



% make OLD=1 default

rm -f *.class

CLASSPATH=.:~/kawa/cvs/kawa-magnetic/kawa-1.7.90-m019-a.jar java kawa.repl
--warn-undefined-variable --main -C reader1.scm

(compiling reader1.scm)

CLASSPATH=.:~/kawa/cvs/kawa-magnetic/kawa-1.7.90-m019-a.jar java kawa.repl
--warn-undefined-variable --main -C reader2.scm

(compiling reader2.scm)

(set-dispatch-macro-character ...) called, I think.

CLASSPATH=.:~/kawa/cvs/kawa-magnetic/kawa-1.7.90-m019-a.jar java reader2

a: 100
