ARGADDR

Message        <Context> taking the address of the constant
               expression "<expression>" in an argument list is a
               language extension.

Description    The HP C compiler will allow the address of a
               constant to be passed as an argument to a function
               call.  This is an extension to standard C.  Other C
               compilers might not successfully compile a program
               that uses this extension.

User Action    Assign the constant to a variable, and pass the
               address of the variable.
