Mmm.. I _think_ that it should include <termios.h>, according to POSIX.
That's where speed_t should be (but I don't have the POSIX stuff here:
it's at the university). So the correct fix would be to just include that
in termcap.h, and then it should work with all kernels.

The #ifdef __linux__ looks a bit suspicious too. speed_t isn't any linux
specific thing, it's quite standard.
