On a typical 64-bit host, using 'int' breaks a GDB command like
"xwhichsymbols Qnil 4294967297", by causing xwhichsymbols
to silently treat the 4294967297 as if it were 1.

For longstanding Emacs code this kind of fix is being put off
until after the release (see bug 9874) but newly-added
code like which_symbols should avoid arbitrary limits
unless there's a good reason to have them.
