Chicken 4 has got a hygienic macro system and thus removed define-macro.
Depending on what you want to do your options are either define-syntax
with syntax-rules or using the low level explicit renaming macro
infrastructure.
Which eggs are you talking about? Maybe this list can give you a
hand in the porting process?
I can feel your pain in the migration progress, chicken 4 has been
around for almost a year now...
Kind regards and all the best,
Christian
