Add support for OpenBSD 
It just rejects the generic System V ABI and has other syscall numbers.

bfc

bfc is a small, fast, self-contained, optimizing Brainfuck compiler for *nix on Intel x86-64. Currently supported targets are Linux and OpenBSD.

Also included are several interpreters in various states of sophistication that document my progress as I was writing this, from the simplest approach to an optimizing JIT compiler.

It’s pretty easy to retarget the compiler, it just means redoing half the work. The compiler itself is platform agnostic.

Building

Build dependencies: a C99 compiler
Runtime dependencies: Linux or OpenBSD

$ git clone https://github.com/pjanouch/bfc.git
$ cd bfc
$ make

To obtain dumps of the intermediate representation, compile with -DDEBUG:

$ make CPPFLAGS=-DDEBUG

Usage

./bfc-amd64-linux [INPUT-FILE] [OUTPUT-FILE]

When no input file is specified, standard input is used. Similarly, the default output filename is a.out. After the compilation, the resulting file can be run on the target platform.
