## 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.
1. `cc src/main.c -O2 -D unigi_flag_platform_null -o unigi.exe`
1. `cc src/main.c -Dunigi_flag_platform_null -o unigi.exe`
## 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.
1. `cc src/main.c -O2 -D unigi_flag_platform_sdl1 -l SDL -o unigi.exe`
1. `cc src/main.c -Dunigi_flag_platform_sdl1 -l SDL -o unigi.exe`
## Advanced configuration
### 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
If fixed point is wished instead of float, one can define `-D unigi_flag_fixedpoint`. This uses the external fptc-lib headers.
