RE: XFree86 4.0.3 / LessTif 0.92.26 Symbol Collision

[Suhaib Siddiqi <ssiddiqi at inspirepharm dot com>]

I do not have an answer to your problem now, unless I compile LessTif under
Cygwin myself.  These symbols are always defined in Xt and MOTIF 2.x
libraries.  However I see your link line has redundencies

> ../../../lib/Xm-2.0/.libs/libXm.a -lXt -lSM -lICE -lX11 \
> -L/usr/X11R6/lib -lXt -lSM -lICE -lX11

Why every library needs to be linked twice?
