But why?  TCC is a compiler, it doesn't generally provide a C library.  
Use newlib or musl or the like for that.

The underlying objection is basically the answer to the question "where 
do you stop?"  So we then would have getopt.  Why would we not have nftw, 
or regexec/regcompile, or getcwd, or any of the other POSIX functions?

So, please no.


Ciao,
Michael.
