No:

    'temacs.exe' is not recognized as an internal or external command,
    operable program or batch file.

I discovered I have 'objdump' from Cygwin; it reports:

address@hidden objdump -f temacs.exe

temacs.exe:     file format pei-i386
architecture: i386, flags 0x0000013a:
EXEC_P, HAS_DEBUG, HAS_SYMS, HAS_LOCALS, D_PAGED
start address 0x001372f0

address@hidden objdump -fh temacs.exe

temacs.exe:     file format pei-i386
architecture: i386, flags 0x0000013a:
EXEC_P, HAS_DEBUG, HAS_SYMS, HAS_LOCALS, D_PAGED

That's very close to the temacs.exe I built from the 24.3.94 tarball; it
has an additional section:

 17 EMHEAP        02a00000  04eaa000  04eaa000  00000000  2**2
                  ALLOC


Is there some other binutils tool that might provide more detailed info
on what's wrong with this file?
