Xt - Needs same DllMain fix for exporting vendorShellWidgetClass?

[Harold L Hunt II]

Xt's Vendor.c has a fix for OS/2 that exports and initializes 
vendorShellWidgetClass on startup.  It seems that this might be needed 
for us since we need the fix for Xaw, Xaw3d, and LessTif.

Would someone please look at the attached patch and comment?  I have 
build tested it and gave it a quick runtime test, but I am not certain 
about whether or not it is needed.
