I found it easier to just replace include/stddef.h with the one
from /usr/include/stddef.h as looking at #ifdef FOO #ifndef
FOO_T #ifdef _FOO_T_ etc. gave me a real headache.

On a somewhat related topic:
Anyone has tried teaching lcc-3.1 to generate *BSD friendly code
(for the 386 arch.)?  It is a real pleasure to see a single
compiler binary that can generate code for MIPS/SPARC/X86 and
weighs in under 256K, runs much quicker than gcc and generates
pretty good code.  The codegen is generated from a machine
definition so presumably one can teach it more tricks and get
better quality code. *And* it is not copylefted.
