Error when building gcc-2.95.2 native compiler on NT-Help needed

[savithri Muthukumar]

Hi,
 I am trying to build gc-2.95.2 native compiler in windows NT
i686-pc-cygwin32 using cygwin.
I was able to configure without any error but when I build
using 'make-bootstrap' command it fails giving the following error
message.
I'm using gnu make.
