Compilation fails with ‘CRTSCTS’ undeclared #2

On Ubuntu 14.04.1 LTS compilation fails:

This can be fixed by using the -std=gnu99 compiler flag instead of -std=c99 (but since I don't know what this does to other platforms, it is probably best to change the Makefile so that this flag is used only on Linux platforms).

I've switched to -std=gnu99 for all platforms and it seems to be okay.
