--- Comment #1 from anlauf at gcc dot gnu.org ---
The warning is not only bogus, but indicates that something goes wrong.

Doing an "nm" on the resulting object files, it seems one equivalence is
missing for names of length 60+.

For z1_59.o:

0000000000000020 C
m2345678901234567890123456789012345678901234567890123456789.eq.0_
0000000000000018 C
m2345678901234567890123456789012345678901234567890123456789.eq.1_

For z1_60.o:

0000000000000020 C
m23456789012345678901234567890123456789012345678901234567890.eq._

It seems it cannot disambiguate the two equivalences any more,
and treat them as a single common.
