FWIIW you can also look at the same kind of discussion I had with
with Rich Felker (dalias) in
 http://www.openwall.com/lists/musl/2014/08/15/8

The "implicit -D__DEFINED_va_list" hack works for Pcc with musl, at least
on i386.

I do not seem to need any such tweak for tcc+musl on i386 but otoh did
not test with the latest versions.

Tcc on x86_64 had to use
 "-D__DEFINED_va_list -D__isoc_va_list=va_list -D__DEFINED___isoc_va_list".
