newlib-1.11.0:target-newlib target-libgloss is not supported under cygwin

[Zhang, Shengqi]

I am trying to build newlib-1.11.0 for target mips under cygwin1.5
i did as the following steps:
$ mkdir objdir
$ cd objdir
$ ../newlib-1.11.0/configure --target=mips-linux

then information was showed:
Configuring for a i686-pc-cygwin host.
*** This configuration is not supported in the following subdirectories:
     target-newlib target-libgloss
    (Any other directories should still work fine.)
Created "Makefile" in /cygdrive/d/software/gcc/newlib/objdir using "mh-frag" and
 "mt-frag"

i made it and i found that nothing had been built.

I want to now why target-newlib target-libgloss cannot be supported.
