You can now do epic things like this:
puts(_gc(xasprintf("%d", 123)));
The _gc() API is shorthand for _defer() which works like Go's keyword:
const char *s = xasprintf("%d", 123);
_defer(free, s);
puts(s);
Be sure to always use -fno-omit-frame-pointer which makes code fast too.

- Polyfill open() w/ O_CLOEXEC on RHEL5
- Remove old workaround from rmdir() on the New Technology
- preadv() and pwritev() are now smarter about demodernization
- preadv() and pwritev() are now available on the New Technology
We can put this back the moment someone requests it. Pain-free garbage
collection for the C language is pretty cool. All it does is overwrite
the return address with a trampoline that calls free(). It's not clear
what it should be named if it's made a public API.
Now when you send a pull request Travis CI will build the entire
repository and run all the tests for you automatically. It takes
approximately two minutes to finish so you can get fast feedback
Cosmopolitan currently doesn't support threads and it doesn't do
anything fancy in longjmp/setjmp so this change was simple to do
- localeconv
- _setjmp (same as setjmp)
- _longjmp (same as longjmp)
- strcoll (same as strcmp)
- flockfile (does nothing)
- funlockfile (does nothing)
- ftrylockfile (does nothing)

The Windows fork() polyfill (which we implement using pure WIN32)
appears to be acting strangely. It's possible a regression was
introduced by recent changes that our tests didn't catch.
This change is workaround so we can upload a new working binary release
to the Redbean website until we can fully fix the problem.

The ucontext_t data structure XNU passes us doesn't appear to be part of
known memory. So we can't use ASAN during the trampoline, which converts
it to a Linux ucontext_t data structure. Please note that this change
doesn't impact the signal handler itself, only the trampoline.
