Fully untested.

Apparently they are not (advertised as?) safe on BSD systems.
We ignore the case of static libraries.

Whitelisted on glibc, Android, and MSVC / mingw.

In an effort to make the algorithm used clear.

Some infrastructures use DEBUG as a generic symbol.

Using a ragel machine.

Using a ragel machine.

Only affects the verbosity of function name printing right now.
