i686-unknown-winnt target not defined

[Niklaus]

Hi ,
 I have compiled binutils successfully with the target i686-unknown-winnt.

 But the make for gcc fails. It says target not supported. I think i
can workaround it using i686-unknown-mingw32.

Few questions
1) Is it a known feature or a bug or something that i am doing wrong ?

2) Do we have something for gcc like configure.tgt for ld and gas of
bintutils. If yes what.

3) Any differences between the targets. If yes what are they

THanks
