The fstat man page (http://linux.die.net/man/2/fstat) claim that additional include files are necessary. Apparently someone changed the interdependency of include files so these are no longer automatically included. Sigh.

It's not that hard to fix: just add the missing includes in the top of the src/base/SerialPort.cpp file...
