This change takes an entirely new approach to the incremental linking of pkzip executables. The assets created by zipobj.com are now treated like debug data. After a .com.dbg is compiled, fixupobj.com should be run, so it can apply fixups to the offsets and move the zip directory to the end of the file. Since debug data doesn't get objcopy'd, a new tool has been introduced called zipcopy.com which should be run after objcopy whenever a .com file is created. This is all automated by the `cosmocc` toolchain which is rapidly becoming the new recommended approach. This change also introduces the new C23 checked arithmetic macros.

# DESCRIPTION
|
||
#
|
||
# This file defines the libraries, runtimes, and build rules needed to
|
||
# create executables from your Linux workstation that'll run anywhere.
|
||
# Loading this package will make certain systemic modifications to the
|
||
# build like turning off the System V "Red Zone" optimization, because
|
||
# αcτµαlly pδrταblε εxεcµταblεs need to be able to run in kernelspace.
