remove includes of qdefs.h and compat.h pr_comp.h: merge pr_comp.h from quake and qfcc, removing the copy in qfcc cmdlib.[ch]: nuke the endian code. qendian.c: initialise the LittleLong etc pointers at compile time rather than run time com.c (both nq and qw): nuke the LittleLong etc init code everything else: fix up after the qtypes.h cleanup
