[Chicken-users] Compilation issue with v4.7.0

[Paul Colby]

Hi,
I tried the following file as a prelude to doing conditional compilation and 
ran into the following snag,

----------------------------- example.scm -----------------------
(define A #t)
(define B 'undefined)
(if A
 (set! B 'good)
 (set! B 'bad))
(print B)
------------------------------ end ----------------------------------

running csi prints out the expected message 'good'
compiling using 'csc example.scm' and running the
executable results in 'undefined' being printed. the
code generated by 'csc -t example.scm' is given below.

BTW I would dearly like to get objc egg to compile.

Regards
Paul Colby

----------------------------- example.c ---------------------------
