In order to improve our chances of success building other open source projects we shouldn't define APIs that'll lead any ./configure script astray. For example: - brk() and sbrk() can break mac/windows support - syscall() is a superb way to break portability - arch_prctl() is the greatest of all horror shows

# 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.
