Hi,

   The directory /usr/src/libc/syscall/ is essential
for hacking the libc code in order to add a new 
system call. 

   Unfortunately, I have been unable to find this
directory from 
libc-5.3.9.tar.gz from ftp://sunsite.unc.edu/pub/Linux/GCC/
or from libc-4.X.

Does anyone have any ideas on this ?

Thank you very much,
