This issue should be closed.

Why do I get “error: dereferencing pointer” when running make?

The message usually is ../src/IoSimple.h: error: dereferencing pointer does break strict-aliasing rules. This is is a false warning issued by an obsolete version of the gcc compiler. Please delete the -Werror flag from the Makefile and run make again.
