okay step one compiled it
So now that I can compile it, how do I make/apply patches to it
asie03/16/2020
the best way is
1. create two copies of the source tree - one called, say, "zzt.orig", one "zzt.new"
2. edit in zzt.new
3. on Linux, diff -Nrup zzt.orig/SRC/ zzt.new/SRC/ > my.patch
on Windows, find GNU diff as a Windows binary and use that
as to apply, likewise, with GNU patch, in the zzt.new/ directory
patch -p1 --binary <../their.patch
