Hi,

After discussing with the MinGW people, we concluded that _M_IX86 is
part of the Win32 platform definition (and there is software that relies
on it), so I intend to add it to the gcc/MinGW specs:

  ... -D__i386 -D__i386__ ...
  ... march=i486:-D__i486 -D__i486__ ...
  ...

will become

  ... -D__i386 -D__i386__ -D_M_IX86=300 ...
  ... march=i486:-D__i486 -D__i486__ -D_M_IX86=400 ...
  ...

etc.

I *think* you are not interested in having this predefined macro in
Cygwin, for the same reason you don't want -DWIN32, but I should ask
you, anyway.

I am not subscribed to the list, so please Cc: to me.

Best regards,
Cosmin
