Looking at the definition of HylaFAXServer just below:

	class HylaFAXServer : public Syslog, public FaxConfig, public IOHandler {

That's 3 base classes == multiple inheritance.

The situation is sort of chicken and egg the definition of the SpoolDir
struct needs HylaFAXServer and the definition of HylaFAXServer needs SpoolDir.

You could try moving the definition of SpoolDir(cutting and pasting) to
below that of HylaFAXServer at the bottom of the header file. and adding a
line where the definition of SpoolDir was:
	struct SpoolDir;
to tell the compiler it is a valid stuct which is defined later.

PS No guarantees!!!!!
