You can't build from the libc directory and you have to configure from 
the top-level.  There are flags you need to have set and passed down 
from the top-level.  In your case, you aren't setting up the -I flags to 
point to the build targ-include or source libc/include directories and 
you are picking up system header files instead of the ones from newlib 
(newlib header files include _ansi.h which has the definition of the 
_DEFUN macro you are getting the error for).

Let's start from the beginning.  Check out the current repository (which 
will eventually become 1.15.0) or untar the newlib 1.14.0 package into 
it's own source directory ($SOURCE_DIR).  The source directory will have 
newlib and libgloss as subdirectories.  Create a separate directory to 
do the build in ($BUILD_DIR).  Try the following (note the --with-newlib 
on the end of the configure)

 > cd $BUILD_DIR
 >$SOURCE_DIR/configure --prefix=`pwd` --target=i686-pc-linux-gnu 
--with-newlib
 >make all-target-newlib install-target-newlib

What happens?
