ddd 3.3.1 on cygwin

[Chris Tsui]

Hi

 

    I tried to compile ddd-3.3.1 on cygwin.  The result is

 Fonts'.xi:1780: Cross reference to nonexistent node `Customizing
 the Execution Window'.reference to nonexistent node `Customizing

 Windows'.:1751: Cross reference to nonexistent node `Toggling

 Debugger Interaction'.reference to nonexistent node `Customizing
makeinfo: Removing output file `/tmp/ddd-3.3.1/ddd/ddd.info' due to errors; use
--force to preserve.
make[1]: *** [ddd.info] Error 2
make[1]: Leaving directory `/tmp/ddd-3.3.1/ddd'
make: *** [all-recursive] Error 1

 

How can I fix this???

 

Thanks in advance.
