## Platform: null ## Platform: null
This platform has a very simple implementation, that is essentially a no-op for any possible target. It's meant for running a basic test before one makes a proper port.

## Platform: sdl1 ## Platform: sdl1
This platform implements the highly compatible SDL 1.2, which runs on all sorts of versions of Linux and Windows, as well as big endian CPUs. This platform implements the highly compatible SDL 1.2, which runs on all sorts of versions of Linux and Windows, as well as big endian CPUs.

### No stdint.h ### No stdint.h
If no stdint.h is available, one must define `-D unigi_flag_nostdint` and also one of `-D unigi_flag_alu_*bit` (`*` = 8, 16, 32, 64), depending on how wide the ALU of the target CPU is.

### Fixed point numbers ### Fixed point numbers
If fixed point is wished instead of float, one can define `-D unigi_flag_fixedpoint`. This uses the external fptc-lib headers. If fixed point is wished instead of float, one can define `unigi_flag_fixedpoint`. This uses the external fptc-lib headers.
