I assume that you are using the pre-built i386-elf toolchain.

This might be problem with the specific revision of the Cygwin DLL which you 
are using. What is the output of the following command when entered at the 
Cygwin bash prompt?

   uname -a

Also, which version of Microsoft Windows are you using? There are known 
problems with certain recent versions of the Cygwin DLL under Win95/98/ME. 
eCos releases are no longer tested under Win95/98/ME.
