Complex. RM places a 64K stack segment limit. As far as I know, GCC requires more than that. Also, GCC was only written for 32-bit machines. My suggestions: a) program GCC to fake 32-bitness by using two 16-bit words b) pack bits (somehow!) to fake a >64K stack segment Samuel Lauber -- _____________________________________________________________ Web-based SMS services available at http://www.operamail.com.
