Testing code with other C compilers

[TimoVJL]

If program code avoid crt, it might be easy to compile it with different compilers.
I use clang-cl.exe as a reference C compiler to see more warnings, but some projects was quite easy to build with clang and with polink with Pelles C libraries.
With clang i saw many unused variables and dead code.

Hi Timo,

Pelles C can detect unused variables too. I guess you found a specific case. Could you share your code if it's possible?
