Is 'verbose' reserved in gcc 2.7.0?

There is a missing ';' after the va_end in verbose().  The va_end
definition in gcc 2.6.3 is lax and doesn't result in an error.  The
definition in gcc 2.7.0 is stricter and does result in an error.

BTW, there is another problem with compiling modules with gcc 2.7.0.
Gcc 2.7.0 conforms to the latest ANSI C++ draft which changed the
scope of variables declared in for statements.  Previously they
remained in scope until the end of the enclosing block.  The now go
out of scope at the end of the for statement.  There are a few places
in module.c and module2.c where variables are used after they go out
of scope.  The change is to simply move the declaration before the for
statement.

Ian M., since this problem is really with the modules package, I
believe this bug report now belongs to you.

And now to Bruce. Here is a simple fix, which makes modules work with
gcc-2.7.0, while keeping it working with a.out/2.6.3.
