A patch for csu/gmon-start.c

[Roland McGrath]

I think your change is ok.  It is usual to use `extern void _end;' and the
like for this, so that &_end has type void *.  Another good choice is
`extern void _end[];' or the like; that has the benefit of `_end' rather
than `&_end' doing the right thing as it does when using a function
declaration.  (Note that `extern void _end;' has the benefit of giving you
an error if you use `_end' instead of `&_end', while your declaration using
a real type can result in confusingly bogus code that fetches from *&_end.)
