I am not so good with Makefiles, so I can see your point on that.

As far as dc, technically dc is not a standard, so if you
standards-conformant behavior, you need to write a bc that can operate
without dc. However, I will also be implementing dc in the same repo
someday. The question is which dc to implement.

About GNU extensions: this was originally implemented for toybox
(, and the maintainer specifically asked
that my bc be able to run
which has basically every GNU extension. Thus, my bc will probably not
fit the suckless philosophy because the GNU extensions need to stay.
Thanks, though.
