Subject: * Split off q_platform.h from q_shared.h * Removed lcc PATH hack and
 replaced with something slightly less hacky * Removed all platform specific
 hostfiles from lcc and replaced with bytecode.c   (from ankon) * Turned lcc
 option "-S" on permanently * Improved q3cpp so that it recursively adds
 include dirs to its list
