Cannot build eglibc with "pthread-functions" errors.

Hi all,

    I tried to build the eglibc. I downloaded the three files from here https://launchpad.net/ubuntu/raring/+source/eglibc.Then,
$ dpkg-source -x eglibc_2.17-0ubuntu5.dsc
$ cd eglibc-2.17/
$ make -f debian/rules patch

$ cd ../

$ mkdir eglibc-build

$ cd eglibc-build
$ ../eglibc-2.17/configure --prefix=$(pwd)

$ make -j8

Now the errors occured.

I looked at the /libpthread/forward.c and found that the line

"#include <pthread-functions.h>"

will include the file "/nptl/sysdeps/pthread/pthread-functions.h" instead of "/libpthread/pthread/pthread-functions.h".

I tried to let it include the right file but it won't work because of my poor knowledge of the patch and the whole eglibc.

Is it  a bug or my wrong operation?
