Indeed, I didn't realize this part of newlib was not built when libgloss is 
used. So my testing there was moot. I could do the same INCLUDES trick in 
newlib/libc/sys/arm/, that should work.

On the other hand, there is already some use of __ARM_ARCH_ISA_THUMB and 
__ARM_ARCH_ISA_ARM in newlib/libc/machine/arm/ before that commit so I guess 
we don't need to include acle-compat.h there?

By the way, what's the reason for passing NEWLIB_CFLAGS explicitely when 
invoking libgloss/<target>/Makefile instead of relying on the export mechanism 
that would allow target Makefile to extend (with +=) the variable?

Best regards,
