#ifndef SUPPORT_VECTOR
/**
* Supported Platforms Tuning Knob (Runtime & Compile-Time)
*
* Cosmopolitan's design allows us to support eight platforms. We enable
* them all by default, since we're able to do eight so efficiently. We
* can't do more, due to the way the 80x86 instruction set is encoded.
*
* The user may optionally tune this bitmask, which effectively asks the
* compiler to leave out system call polyfills for a platform, which may
* offer marginal improvements in terms of code size and performance, at
* the cost of portability.
* Tuning this bitmask will remove platform polyfills at compile-time.
