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.
