My compiler is much smaller, compiles much faster, and generates only slightly
worse code -- but I won't touch it :-). I ran a stupid benchmark:

[z.c is essentially 32768 lines `i=1;' where `i' is auto int. rcc is
the main stage of lcc. It must be doing something strange for the
user+sys times not to add up to nearly the real time and bad buffering
for the system time to be so large.]

We also need support for asm, inline, -fpic, a standard assembler, ...

This doesn't help. You have to modify it to support long long...
