BLTINIMPLRET

Message        <Context> for the function "<name>", the implicit
               return type of "<type>" is not consistent with the
               expected type of "<type>".  It will be treated as an
               ordinary implicitly defined external function.

Description    A function that could be handled internally by the
               compiler has not been declared, so an implicit
               declaration has been created for the function.  The
               return value for the function is being used, and the
               implicit return type does not agree with what the
               compiler expected to see.  In such cases, the
               function will not be handled internally, but will
               instead be called at run time in the usual manner.
               This could result in a performance loss, or possibly
               incorrect results if the implicit return type is
               incorrect.

User Action    If the function is intended to refer to the runtime
               library routine, the appropriate header file should
               be included in the source.  Alternatively, a correct
               prototype could be provided privately in the source
               file.  If the function is intended to be a
               replacement for the runtime library routine, disable
               the intrinsic version by specifying "#pragma
               function(function_name)" in the source file.
