svn commit: branches/uClibc_0_9_28: include/sys

[andersen at uclibc.org]

Author: andersen
Date: 2007-02-01 18:24:29 -0800 (Thu, 01 Feb 2007)
New Revision: 17720

Log:
As with uClibc trunk, note that the _syscall#() macros are for uClibc internal
use only.  User application code should use syscall() instead.
