Reporting possibly unbound variables

[Ludovic Courtès]

Hello,

I just committed support for ‘-Wunbound-variable’:

  
http://git.sv.gnu.org/cgit/guile.git/commit/?id=f67ddf9dbfec851676806a2f3dff7eae539ac499

It works pretty well, except for occurrences of ‘define-class’ et al.,
which lead to false positives because the code generated by these macros
doesn’t use ‘define’ (this is to make sure a top-level binding is
created, not a lexical one.)

Ideas on how to “fix” it?

(Presumably I won’t work on it again until after 1.9.4.)

Thanks,
Ludo’.
