That's fine.  A return statement or exit() call is unnecessary
in main() due to a special-case rule that was added in 1999 for
compatibility with C++.  I don't particularly like that rule myself.
I choose to omit the return statement in small programs, but if
you want to add the "return 0;", I have absolutely no objection.
(I used to do that myself.)  It even makes your code more portable
to old compilers that support C90.  (tcc claims to support C99,
but it has a bug in this area.)

 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".)
 

Godbolt has support for tcc, which might be convenient if you want to look at its output.
