I was going by the gmp.h changes.  The declarations removed from that
file appear to be for just these two, not dozens of others.

Even better then.  My concern was to make reasonably sure we could have
libgmp.so.3 and libgmp.so.10 coexist for a while in the Debian archive,
and that the risk of crashes due to both versions being loaded in the
same address space would not be too high.  Removed functions aren't a
problem for this.
