OK, will try.  Found a couple already, but they weren't sid specific.

That's not sufficient to determine a solution to this issue, though:
the build-libiberty doesn't create a shared library unless it is passed
--enable-shared.  Do you mean with this that build-libiberty should
enable shared if neither --enable-shared nor --disable-shares is passed?
If yes, then I guess that needs discussion needs a libiberty maintainer.
If no, then I don't understand how you can enable shared in sid when it
is not enabled in libiberty.

The problem isn't the "const char*" in the struct mep_idesc, but the
char* in CGEN_BITSET that is being initialized with string constants
like "\x80".  This is defined in include/opcode/cgen-bitset.h.
