anonymous class type error

[Arati D]

I am getting the following error during make stage.

/src/winsup/w32api/include/winnt.h:1707:anonymous class type not used to
declare any objects

while compiling the file src/winsup/cygwin/assert.cc

My environment :
configure --target=i586-cygwin32
gcc2.95.3 
binutils2.11
newlib 1.9.0 from www.cygwin.com (libiberty, newlib, winsup, include)


how do I go about this error ?
