Justine Tunney 3ab76b2312 Fix cosmopolitan.h for C++ 
We now have an integration test that runs the amalgamated sources
through a C++ compiler, to prevent the recurrence of such issues.

Fixes #38
Thanks @gbbnfhb for the report!

Cosmopolitan

Cosmopolitan Libc makes C a build-once run-anywhere language, like Java, except it doesn't need an interpreter or virtual machine. Instead, it reconfigures stock GCC to output a POSIX-approved polyglot format that runs natively on Linux + Mac + Windows + FreeBSD + OpenBSD + BIOS with the best possible performance and the tiniest footprint imaginable.

Background

For an introduction to this project, please read the αcτµαlly pδrταblε εxεcµταblε blog post and cosmopolitan libc website. We also have API documentation.

Getting Started

Here's how to get started with the freestanding hermetically-sealed monolithic source repository:

tar xf cosmopolitan-0.1.2.tar.gz  # see our releases page
cd cosmo
make -j12
o//examples/hello.com

Here's how to get started with the amalgamated binaries, which let you bring your own build system:

unzip cosmopolitan-amalgamated-0.1.2.zip  # see our releases page
echo 'main() { printf("hello world\n"); }' >hello.c
gcc -g -O -static -fno-pie -no-pie -mno-red-zone -nostdlib -nostdinc \
  -o hello.com.dbg hello.c -Wl,--gc-sections -Wl,-z,max-page-size=0x1000 -fuse-ld=bfd \
  -Wl,-T,ape.lds -include cosmopolitan.h crt.o ape.o cosmopolitan.a
objcopy -SO binary hello.com.dbg hello.com
./hello.com
