I can't see from the ChangeLogs or svn logs of config.sub / config.gcc when

it happened, but configure now says arm-netbsd is not supported, so closing

this as WONTFIX.

arm-pe and arm-wince-pe targets have now been removed from GCC.

I've created PR47093 for that.
When the build merely hit a -werror-always issue, I made the PR block 44756,
and PR 44756 blocks PR47093.
Of course, a --enable-werror-always issue might mask a hard failure later on.

I gave my own suggestions for deprecations in 
 - there are some 
overlaps with the non-building targets (Interix, some a.out BSD, crosses 
to alpha*-dec-osf5.1* without GNU as don't build).

Joern, can you create a meta-bug to track the various non-building target
configurations?  It would be nice to have a single place for an overview
(and a possible list of targets to deprecate).

arm-netbsd appears unmaintained.  Apart from the desirability of moving 
NetBSD to EABI, there's a clear bogosity in arm/netbsd.h I noticed a while 
back:

/* Although not normally relevant (since by default, all aggregates
   are returned in memory) compiling some parts of libc requires
   non-APCS style struct returns.  */
#undef TARGET_RETURN_IN_MEMORY

That's a target hook, not a macro.  The #define is in arm.c; the #undef 
has no effect.  Presumably a broken conversion from macros to hooks, not 
noticed for lack of anyone using recent GCC for this target.

The arm-pe / arm-wince-pe targets are saddled with another unused function:
../../../gcc/gcc/config/arm/arm.c:4874:1: error:
‘arm_handle_notshared_attribute’ defined but not used [-Werror=unused-function]

Declaration and definition depend on TARGET_DLLIMPORT_DECL_ATTRIBUTES, but the
only use also depends on !defined(ARM_PE), and the declaration has no
ATTRIBUTE_UNUSED marker.
