Ok, I've got it compiled now.  Here's what I did to make it compile under RHEL/x86_64.
Install GCC 4.3.2:
	Code:
	yum install gcc43 gcc43-c++
 ----------------
Modify the following files:
	Code:
	EMuShareMem/makefile
world/makefile
zone/makefile
eqlaunch/makefile
mailserver/makefile
chatserver/makefile
 In each of these, replace all instances of "gcc" with "gcc43", and remove "-march=i686" from the COPTS section(if present).
----------------
Modify utils/Makefile:
Replace all occurances of  "g++" with "g++43".
----------------
Modify common/TCPConnection.h as follows:
	Code:
	#else
        size_t addrlen;
#endif
 becomes
	Code:
	#else
        socklen_t addrlen;
#endif
 ----------------
Modify common/crc32.cpp as follows:
	Code:
	//#if !defined(i386)
//#define i386  // If you are on a non-Intel based platform (Sparc/HP/NEC/etc), you will want$
//#endif
 becomes
	Code:
	//#if !defined(i386)
//#define i386  // If you are on a non-Intel based platform (Sparc/HP/NEC/etc), you will want$
//#endif
#undef i386
