It will be a while before I can migrate away from Chicken 4 so count me
among those who would be appreciative of any porting of
fixes/improvements from chicken 5 to 4. I'm keen on getting to Chicken
5 as soon as possible but it is a large task and is likely to take six
months to a year.

NOTE: Aside from the effort in porting the code there are still a few
dependencies on eggs that have not been ported. Triming dependencies
may eliminate some of these. A quick crude scan of use statements gave
me this:

call-with-environment-variables
csv
csv-xml
dot-locking
foof-loop
hostinfo
pathname-expand
ports
regex-case
rpc
s11n
sparse-vectors
srfi-12
srfi-19
tcp
