This one is a long-standing issue:

  - this is a static build,
  - son SDL libraries linked to by chocolate-doom ars C++ libs,
  - one library (indirectly) linked to by chocolate-doom needs libz
  - chocolate-doom itself is written in C

So, chocolate-doom uses gcc to link, instead of g++. In so doing, it
bring in neither libstdc++.a nor libz.a

I did a quick hack to verify this, and added -lstdc++ and -lz to the SDL
Libs.Privte in sdl.pc, and the build suceeded.

For the C++ dependency, SDL unconditionally checks for a C++ compiler:

    AC_PROG_CXX

so we should probably add a dependency on C++ to SDL.

As for the the -lz, I'm still investigating...

Regards,
Yann E. MORIN.
