And here the 2.1 gnu-patch worked fine, and reported no errors using the
same patches, on the same sources (both from the FTP directory), on the same
platform (OSF/1 Alpha).  Since I can't reproduce the problem here, I'm
giving up on that one.

Yes, but it makes a difference whether you invoke the compiler as "gcc" or
as "g++" on the same source, even if g++ is a link to gcc.  The compiler
actually checks argv[0] to see how it was invoked and behaves differently in
the two cases, since C++ is not just a superset of standard C.  For example,
compiling and running the following program would have to return a different
value if you used gcc (4) than if you used g++ (1), because it is impossible
to tell from the source whether it is C or C++, and the program behaves
differently depending on whether it is interpreted to be ANSI C or C++:

int
main()
{
        return sizeof('a');
}

If you want to compile C++ code with gcc, you have to invoke it as "g++".
