small patch to gdbserver to make it compile under linux 2.2.5

[Marco Molteni <molter at csl dot sri dot com>]

Hi,

I'd like to contribute a small patch I did to the gdbserver source
(from the gdb-4.18.tar.gz distribution) in order to make it compile
under Linux.

The Linux kernel version I used is:2.2.5-15smp
The compiler is egcs-2.91.66

If you like, I can also contribute a patch to make gdbserver to
control the remote host IP address before accepting the connection
(now gdbserver happily accepts the first connection request).

I hereby give the copyright of my humble patch to the FSF or to who is
needed to make you accept the patch.

Best regards
Marco
