line and auth_level's redefinitions are just extraneous telnetd will #define extern and then include ext.h to allocate storage for all of these extern'd vars; however, two of them are actually defined in libtelnet instead. Instead of doing an #ifdef extern dance around those function pointers, just add an EXTERN macro to make it easier to differentiate by sight which ones will get allocated in globals.c and which ones are defined elsewhere.
