Windows
On windows using Cygwin, U/WIN or Interix, LessTif must be built as
static libraries. Because, one of the biggest issues with X on Win32 is
the moronic DLL format. Specifically - it is not possible to export
data from a Win32 DLL in a form that can be used to statically
initialize another global variable. Data access from a DLL requires at
least one pointer indirection, and hence executable code. This is why
X11R6 doesn't have DLLs for Xt/Xmu/Xaw (and Motif) on Win32.
Not exactly true on Cygwin anymore because of the following hack:

I am still trying to shake out a working lesstif DLL from this, but I
thought I would ask two questions that might help speed this up.
Does anyone remember what variables specifically this effects? Is
_XtInherit() the only one?
As an intermediate step, I am trying a static lesstif build with the new
shared Xt/Xmu, etc. I am getting the followin message on startup of an
application that previously worked fine:
Warning: XmManager ClassInitialize: XmeTraitSet failed
Error: attempt to add non-widget child "DropSiteManager" to parent "he"
which supports only widgets
Still digging in lesstif source to find out what this means and where to
go from here, but any comments/suggestions would be greatly appreciated.
Thanks.
