I wanted to try gzjoin utility to join and concatenate multiple Deflate streams but it is located in the examples folder and doesn't build with make.
It would be great to add a simple Makefile for all that tools in examples folder.

P.S. For those who are looking for a command to compile gzjoin on Linux: cc -I/usr/include gzjoin.c -o gzjoin -lz ; chmod +x gzjoin
