Helo Richard,

your right. The real name of the _REAL_SERVER() function is something
like _REAL_SERVER_..._... .You can find the name out by typing:
"nm lib...++.a | grep _REAL_SERVER_" . But a workaround could be, to compile
you c program with a c++ compiler and using "extern "C" {...}" for the
real c-code like "#include<stdio.h>. Then the compiler handles _REAL_SERVER
by default correct. A modern C++ compiler should be able to compile any ansi-c
code. 

Michael :-)
