A minor point: The latest unreleased version of tcc appears to fix this
bug.  In tcc 0.9.27, falling off the end of main (defined as "int
main(void)") returns some random status.  In the latest version, it
returns 0, based on a quick experiment and a cursory examination of the
generated object code.  (tcc doesn't have an option to generate an
assembly listing; I used "tcc -c" followed by "objdump -d".)
