No patch attached....
The CYGBLD_ATTRIB_UNUSED attribute addition is fine (and obviously you'll need
to add that before the other patches I approved tonight).
However I just want to check about the CYG_REFERENCE_OBJECT change, as far as I
can tell the "used" attribute still applies to variables. e.g. here:
http://gcc.gnu.org/onlinedocs/gcc/Variable-Attributes.html
and more specifically here:
http://gcc.gnu.org/viewcvs/branches/gcc-4_6-branch/gcc/doc/extend.texi?content-type=text%2Fplain&view=co
and there's no mention of it being removed here:
http://gcc.gnu.org/gcc-4.6/changes.html
Unless, of course, they failed to keep their docs in line with reality, but it
seems unlikely. Is there some alternative explanation for why you were having
trouble with it in CYG_REFERENCE_OBJECT?

Where the CYG_REFERENCE_OBJECT() macro was being used, I was getting a compiler
warning about the "used" attribute being ignore. Somewhere in the gcc docs, I
found two tables of attributes -- one table for functions and one for
variables.
The "used" attribute was in the function table but not the variable table.
I'll
try to find those tables again.

The 4.6.3 manual certainly shows "used" being a valid attribute for a variable.
Can we split this up and commit the CYGBLD_ATTRIB_UNUSED definition now so that
I can go ahead with the other patches that depend on it? What's the "right"
way to split a bug into two?

Perhaps you don't need to split the bug, just split the patch in two
attachments.

I don't think we even need to be as formal as that between maintainers, not
with a change this small anyway - no need to attach an updated patch to this
bug for just the CYGBLD_ATTRIB_USED portion; just go ahead and commit that bit
by itself, although with a ChangeLog still.

Has anyone come up with a solution to CYG_REFERENCE_OBJECT? It does not work
with gcc 4.6.3 or 4.7.3.
