+<para><function>chroot</function> only emulates a chroot function call

+related function calls.  A real chroot functionality is not supported by
+Windows however.</para>
+
+<para><function>clock_getres</function>, <function>clock_gettime</function>

+
+<para><function>link</function> will copy the file if it can't implement
+a true hardlink.  This is true at least for FAT and FAT32 filesystems.
+NTFS supports hardlinks.  </para>
+
+<para><function>lseek</function> only works properly on binary
+files.</para>
+
+<para><function>setuid</function> is only safe against reverting the user
+switch after a call to one of the exec(2) functions took place.  Windows 
+doesn't support a non-revertable user switch within the context of Win32
+processes.</para>
+
+<para><function>vfork</function> just calls <function>fork</function>.</para>
+
+<para><function>vhangup</function> always returns -1 and sets errno to
+ENOSYS.</para>
