The i686 is never defined in imakemdep_cpp.h. So this must be a default
define from cpp.
$ gcc -dM - -E </dev/null
...
#define i386 1
#define i686 1
...
$ i686-pc-cygwin32-gcc -dM - -E </dev/null
...
#define i386 1
...
I'm sure you also have a #define i686 for the cygwin-gcc
And please check config/cf/Imake.cf
#ifdef linux
...
XCOMM Keep cpp from replacing path elements containing i486/i586/i686
...
# ifdef i686
# ifndef i386Architecture
# define i386Architecture
# endif
# undef i686
# endif
...
So this seems to be normal. For cygwin, there is
#ifdef __CYGWIN__
#define MacroIncludeFile <cygwin.cf>
#define MacroFile cygwin.cf
#define cygwinArchitecture
#define i386Architecture
#undef i386
#undef __i386__
#undef _X86_
#undef __CYGWIN__
#endif /* CYGWIN */
We just have to add #undef i686, #undef i486, #undef i586 here
bye
