It may be better to fix gcc. However, you can try to convince the ddd
maintainer.

What I was referring to is that in the curent lesstif version, the
compatibility
mode is hard-coded at build time. Therefore, there is no compatibility
switch to play with once lesstif is installed.

Please try on Cygwin:
>cat Xmcheck.c
#include <Xm/Xm.h>
#include <stdio.h>
int main(void){
  printf("xmUseVersion=%d XmVersion=%d\n",
         xmUseVersion, XmVersion);
  return 0;
}
>gcc -Wall -I/usr/X11R6/include Xmcheck.c -L/usr/X11R6/lib -lXm
>./a.out
xmUseVersion=2002 XmVersion=2002

If it gives different numbers, there is a good chance that your lesstif
library won't work properly.
