Arnaud, the problem is with both "#pragma interface" and "#pragma

Guarding all "#pragma interface" and "#pragma implementation" calls with 
ifndef __CYGWIN__

allows everything to compile cleanly - is this something that could be 
applied to the main baseline?

Is the following what you are referring to?

"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."

If yes, these rules have been changing.  Brian, isn't this what you 
were specifically working on recently?
