Problems building 4.8 branch

[Eric Norum]

I checked out the 4.8 branch of RTEMS.  When I try to build it I get:
.

m68k-rtems4.8-gcc --pipe -DHAVE_CONFIG_H   -I.. -I../../

I configured the build with:
/usr/local/rtems/src/cvs/rtems-4-8-branch/rtems/configure --prefix=/ 
usr/local/rtems/rtems-4.8 --enable-cxx --disable-rdbg --enable- 
tests=samples --enable-networking --enable-posix --target=m68k- 
rtems4.8 --enable-rtemsbsp=uC5282

The compiler is:
rt> m68k-rtems4.8-gcc --version
m68k-rtems4.8-gcc (GCC) 4.2.1

I believe that this is a relatively recent addition to the network  
code.  Did some header file get missed from the CVS commit?
