[Bug c/7544] [3.3/3.4/4.0 regression] #pragma weak problem

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The bug, as described, is a bug and is still present.  The thread
referenced talks about the case where foo isn't declared, but the bug
is about the case where bar isn't declared.  Where bar isn't declared, but
foo is defined in that translation unit, 2.95 generates output which assembles
to an object file with a weak alias, while current GCC doesn't.  Per Sun's
specification <http://docs.sun.com/source/817-5064/sun.specific.html#48658>,
this is a bug.

#pragma weak bar = foo
void foo(void) {}

generates symbols

00000000 W bar
00000000 T foo
00000000 t gcc2_compiled.

with 2.95,

00000000 W bar
00000000 T foo

with 3.0, but just

00000000 T foo

with later versions.  The manual referred to in the referenced thread is
an old C++ manual and so irrelevant to this bug.

Setting milestone to 4.0.0 as not expecting to fix this on earlier branches.
