It is safe to use these standard includes and its contents:
-<tt/assert.h, conio.h, dio.h, errno.h, geos.h, joystick.h, mouse.h, stdlib.h, string.h, time.h/
+<tt/assert.h, conio.h, dio.h, errno.h, em.h, geos.h, joystick.h, modload.h, mouse.h, stdlib.h, string.h, tgi.h, time.h/

It was not tested enough, but functions from these includes might work under GEOS:
<tt/rs232.h, zlib.h/
