It would've been helpful if you had supplied (after looking at it yourself
of course) the preprocessed source for the affected file.
  
  $ make CFLAGS=-g all-gcc

should've done the job. And, please do mention what gcc sources you're
using!

I remember another user who ran into something similar, and the cause
was one of the target files (arm.h?) was defining a macro called "Hint" 
which caused havoc for a structure member named "Hint" in winnt.h file.
This was with gcc-2.95.x source base.

As far as I can tell, this problem is now fixed in the dev sources, 
where the macro Hint is moved into arm.c file instead and doesn't 
encroach into user namespace.

Since I don't know what your winnt.h:2053 contains, it's just a guess,
but I'd bet it's something of that nature. If it is so, rename Hint to
ARM_HINT or something like that and rebuild.
