Re: [Chicken-users] Error: illegal bytevector syntax: unspecified

[Todd Dukes]

It is disapointing that this doesn't work:

      (cond ((null? remaining) (cond-expand (bigloo
                                             #unspecified)
                                            (else
                                             #t)))

It returns the same error. I assume that the cond-expand is not
operated on until after the file is parsed.

I can easily work around this case by using

      (cond ((null? remaining) #t)

But I am worried now that other cases may not be as easy.  I guess in
that case I can do a cond-expand around an include.  I will write a
short test to see if that will work.
