Incompatibility in aspell which causes the program belly-up.

The use of th "-a" option,"ispell -a" compatibility mode caused aspell to 
die with the unintuitive error message: 
   ==>  Error: nroff: dlopen returned "No such file or directory".

This appears to happen in the pipe() function.  I am not a oop programmer so its gets \
kind of hard to follow.  One of you familiar with c++ and the code .. please take a \
look at this.


$ aspell -a
   ==>  Error: nroff: dlopen returned "No such file or directory".

Does this happen systems other than cygwin?

All I used was gdb's n so I don't know how gdb jumped to L# 47 of stack_ptr.hpp

Help me track down this bug, so that the many people who are forced to use cygwin can \
benefit from using the aspell program as well as cygwin emacs users.
