You should have waited for a message from the gdb list... But your problem
is very simple: you're buiding for "powerpc-linux-gun". You cannot build
for one OS on another OS. It doesn't (usually) work.

Are you targeting powerpc-linux??? If so, build it on your powerpc-linux
box. If you are building for generic powerpc-eabi or something, then use
"powerpc-eabi" as a target.

Thanks Keith,
No and Yes,
No, I'm not trying to build a GDB that run on linux, what I am trying to do 
is to build a GDB that runs on NT4.0/Cygwin.
And, Yes, I'm trying to build a GDB for powerpc target that run on Cygwin.

so in conclusion, I need to be able to debug a PowerPC target from NT/Cygwin.

Try a newer GDB version.  I believe this is caused by a change in
headers in Cygwin very recently; you may need a current CVS snapshot in
order to fix it.

Huh?  I build Solaris-x-Linux and Cygwin-x-Linux debuggers fairly
frequently.  Cross debuggers take some care not to use target-specific
headers in the target-dependent files for exactly this reason.

You can, of course, and it usualy works, provided that you have
installed the target OS headers and libs in the appropriate places.
