[Tinycc-devel] tcc -v with mob date?

[Christian Jullien]

Hi,

Currently, tcc –v displays the (mob) githash which helps to identify which this 
version comes from.
It is not however user friendly.

I would like to add last commit date as:

jullien@sims4:~/tinycc $ ./tcc -v
tcc version 0.9.27 mob:afcdaf1 on 2022-11-29T00:56:26-06:00 (ARM eabihf Linux)

Maintainers, can you please apply a patch similar to this one?
