Probably you're right. I don't know the history of this #define but
according to GCC documentation, "All names which begin with two
underscores, or an underscore and a capital letter, are reserved for the
compiler and library to use as they wish." So __WIN32__ should not be
defined for the tools, which are just applications, if it's not
pre-defined by the compiler. But #define is not the only problem. When I
worked around the #define, mkimage was built with incorrect endianness,
so I had to investigate the problem and found the includes order issue,
which is fixed by the patch.

I don't know if anybody needs them. There is Makefile.win32 in the tools
directory so maybe somebody builds the tools on Win32 platform, though I
suspect that nobody does. Maybe Wolfgang can answer your question...
