Hi tech@
While trying to build a kernel with option DEBUG, I came across the
following errors:
cc1: warnings being treated as errors
../../../../lib/libz/deflate.c: In function 'check_match':

The following diff fixes the z_verbose issue:

But I was not sure how to add in the include for fprintf, stderr, and putc.
Any clues would be appreciated.
Thanks
