Hi Michael,

I'm currently working on implementations of the __has_*() operators,
that is indeed much larger than the initial patch, but at least it
doesn't feel "wrong" or awkardish. But if __TINYC_MOB__ was going to
be merged, I think there would be no problem in counting commits from
the initial one, but I don't think it would be really useful anyways,
since the macro wouldn't be present in older versions.

The second patch I'm working on does exactly that, the attributes' and
builtins' names are taken from TCC's source code (since they're
already compatible with GCC/Clang), and the features' names are taken
from the "Clang Language Extensions" page [1], because GCC doesn't
seem to specify them in their "C Extensions" section [2], but I might
be wrong, so feel free to correct me.
Regards,
Álvaro.
