Problems compiling EGLIBC 2.17/nptl/pthread_spin_lock.c with Cygwin-built cross GCC 4.7.2

[Jacob Kroon <jacob dot kroon at gmail dot com>]

Hi,

I'm trying to compile EGLIBC 2.17 for ARM in Cygwin, using a cross GCC
4.7.2, which is also built in Cygwin using native GCC-4.5.3.
I've managed to get around the problems with the "install-headers"
target by patching "eglibc/libc/sunrpc/rpc/types.h",
but now when I do the actual full compile I get infinite file
inclusion recursion in nptl/pthread_spin_lock:

...

The compiler flags includes "-I../ports/sysdeps/arm", I think this is
the reason for the infinite inclusion. But I can't decrypt the eglibc
Makefiles, could anyone point in the right direction, and
maybe suggest a fix ?
