[syslinux] Enable debug messages for gpxelinux.0

For several days, I've been trying to debug an issue booting a Windows 7 machine over iscsi (utilizing gpxelinux.0 and sanboot.c32). 
    - I can get it to function OK utilizing plain gPXE (so I know my iscsi config is OK and also the iscsi drive is OK). 
    - When utilizing gpxelinux, the system shows that the iscsi drive is mounting and trying to boot. However, at that point the system hangs.
To troubleshoot this issue, I'm trying to enable the debugging messages in int13.c 9 (which is called by iscsiboot.c). I'm not having any luck (I've already recompiled gpxelinux.0 enabling the gpxe gdb debug options per the gpxe website). Can someone point me in the right direction on how to get gpxelinux.0 debug information?
