--enable-final

Concatenates all .cpp files into one big .all_cpp.cpp file, and compiles it in one go, instead of compiling each .cpp file on its own. This makes the whole compilation much faster, and often leads to better optimised code, but it also requires much more memory. And it often results in compilation errors when headers included by different source files clash one with the other, or when using c static functions with the same name in different source files.

This is a good thing to do at packaging time, but of course not for developers, since a change in one file means recompiling everything.
