unreferenced symbol __cg92_used when compiling Pro*C programs

Hi, world !

Could anyone please help me with ORACLE 7.1.3 and Pro*C 1.6 ( and 2.0 ) ? After installing server on my Sun host, I've tried to compile Pro*C examples in $ORACLE_HOME/proc/demo with gcc.
There is "proc.mk" file there - so I typed "make -f proc.mk sample1" - but :-(.....

First of all, gcc doesn't know language "cg92" ( through command line option -xcg92 ) - that was the reason for some warnings, but finally ld could not find referenced symbol "__cg92_used". What does it mean ?

I couldn't catch any reference to this symbol looking through manuals or Oracle*books.

Any ideas and suggestions would be greatly appreciated .

Thanks,
Anton
