Re: remote XOpenDisplay in Solaris (SunOS 5.6)

Well, I guess that's why it's good form to prefix function names
with an abbreviation based on the module- or application-name.

In contrast, I was able to get some degree of control (not much)
over Motif's nonsensical stacking order by #define-ing XtManageChild
and XtUnmanageChild to have my own function calls intercept them
before handing them off to these undisciplined (and downright
hostile and obstinate) functions.
