Thanks to Joe for his great help with this, both on-list and off.  As 
his later references to "gologit2b" suggest, there is a beta version 
of gologit2 that supports these other links (e.g. loglog and 
cloglog), but part of the reason I haven't released it yet is because 
I wanted to resolve inconsistencies in terminology across software 
packages.  I'll release the program (or perhaps a spinoff of it) 
eventually, but in the meantime if anybody has a desperate need for 
an ordinal cloglog or loglog program (like ologit and oprobit but 
using the cloglog and loglog links) email me and I'll tell you how 
you can access the beta version.
