The obvious cure for this problem is to change ORIGINAL_NM_FOR_TARGET into
ORIGINAL_NM_FOR_TARGET = ../binutils/nm-new
But it is not addressing the real issue whatever that might be.
I'm unable to suggest the real fix for this problem without further
investigation and probably more importantly understanding what the rules
are for .exe extension according to cygwin. Somehow I would naively
expect to see nm-new.exe instead of nm-new as file inside your binutils
BTW, can you look what EXEEXT and EXEEXT_FOR_BUILD are at the end of
builddir-risos/binutils/config.log ? I guess both will be:
while I would expect:
If so, that might be the issue we need to solve.

If you would restart the build from scratch you would run into exactly
the same problem again because your gcc/Makefile change is a change in
a build generated file. So try to restart the existing build by:
$ cd builddir-riscos
If that succeeds, then do "make install" and apart from the RISC OS
specific programs (cmunge, elf2aif, somanager, etc) living in 'riscos'
subdirectory, you already have your own RISC OS compiler built (output
BTW, it could be that you bump into the same issue for objdump. Do the
same hack and see if you can continue again.
