Customer environment:
Product: Tuxedo 8.1 
Platform: HPUX 11i 
All the prerequisites for Tuxedo 8.1 are satisfied. 
Compiler - ACC HP Ansi C++ B3910B A.03.37

Problem description:
When compiling  the program using macro UDEFERSIGS()  customer is getting the following error:
/usr/ccs/bin/ld: Unsatisfied symbols:
_e_sigpending_addr() (code)
_e_sigdefer_addr() (code) 

The problem seems to be with  macro definition for some functions in the "$TUXDIR/include/Usignal.h" header
that don't have necessary instructions to be compiled with a C++ compiler. 
The only way to succesfully compile this code was to modify the "Usignal.h" header file in order to declare
those two functions as ' extern "C" ' if the precompilation  flag "cplusplus" is active.
