You can now call functions like fork() from Lua and it'll work across
all supported platforms, including Windows. This gives you a level of
control of the system that Lua traditionally hasn't been able to have
due to its focus on old portable stdio rather modern POSIX APIs. Demo
code has been added to redbean-demo.com to show how it works.
This change also modifies Lua so that integer literals with a leading
zero will be interpreted as octal. That should help avoid shooting in
the foot with POSIX APIs that frequently use octal mode bits.
This change fixes a bug in opendir(".") on New Technology.
Lastly, redbean will now serve crash reports to private network IPs.
This is consistent with other frameworks. However that isn't served
to public IPs unless the -E flag is passed to redbean at startup.

SYNOPSIS
System Five Import Libraries
OVERVIEW
Bell System Five is the umbrella term we use to describe Linux, FreeBSD, OpenBSD, and Mac OS X which all have nearly-identical application binary interfaces that stood the test of time, having definitions nearly the same as those of AT&T back in the 1980's.
Cosmopolitan aims to help you build apps that can endure over the course of decades, just like these systems have: without needing to lift a finger for maintenance churn, broken builds, broken hearts.
The challenge to System V binary compatibility basically boils down to numbers. All these systems agree on what services are provided, but tend to grant them wildly different numbers.
We address this by putting all the numbers in a couple big shell scripts, ask the GNU Assembler to encode them into binaries using an efficient LEB128 encoding, unpacked by _init(), and ref'd via extern const. It gives us good debuggability, and any costs are gained back by fewer branches in wrapper functions.z
