pardon my obtuseness: I'd like to build newlib for the arm-none-eabi target on a Cygwin host.

I have a arm-none-eabi GCC and Binutils which was built for native Windows.

Cygwin != native Windows.  If you want to use a Cygwin shell for
cross-compiling, then you'll want Cygwin-hosted cross-compilers.

I have downloaded newlib-cygwin in directory ./newlib-cygwin .  I create a directory ./newlib-cygwin-arm, and

$ export CC=arm-none-eabi-gcc
$ cd newlib-cygwin-arm
$ ../newlib-cygwin/configure

That is not how cross-compiling works.  Cross-compiler toolchains
(binutils/gcc/gdb/newlib) are built by configuring with the desired
--target.

i think you mean --host

No, I didn't.
