I've been slow replying to this, partly because I didn't think dynamic
loading worked on SunOS 4 at all.  But this problem is presumably generic
to all systems without a working RTLD_GLOBAL.  The most obvious way round
it is to arrange for complist and zle to share symbols via comp1.c,
like zle and compctl already do.  Maybe that's not too hairy?
