It seems that no dummy return is required if a "throw" is directly preceding
the end of function. But as the omniORB source sometimes uses the
OMNIORB_THROW macro which calls another function (omniExHelper::name) which
throws an exception, there is no way for the compiler to know that the
function doesn't return and it therefore complains about the missing
return/return value.

BTW, I get warnings ("control reaches end of non-void function") for lines
3930, 4234, 4342 in typecode.cc from my gcc 2.95.2/Linux - these are exactly
the functions which use the OMNIORB_THROW macro. Functions with a "throw"
and no return statement are ok (e.g. typecode.cc, line 860).


bye, Christof
