Supporting Linux 2.0 may be nothing but a burden for developers,
but for some users it is badly desired.
The following is what I did to make the current kaffe run on my
old Linux machine. I would NOT insist that this should be
officially supported. This is only for reference.
1. Patch libraries/clib/native/Double.c
Strtod() of my Linux is buggy. So I got a reliable source of
strtod.c from somewhere and put it to libraries/clib/native
and make Double.c include it.

2. Patch replace/getifaddrs.c
Old Linux does not have linux/netlink.h and linux/rtnetlink.h.
So I do not expect kaffe to use replace/getifaddrs.c.

3. Install getaddrinfo.
Get getaddrinfo-1.5.1.tar.gz from
http://www.sra.co.jp/people/m-kasahr/getaddrinfo/
and compile getaddrinfo.c. This program provides
getaddrinfo() and getnameinfo().
Put getaddrinfo.h to libraries/clib/net/
Then insert the following lines to
libraries/clib/net/InetAddressImpl.c
libraries/clib/net/NetworkInterfaceImpl.c
libraries/clib/net/PlainSocketImpl.c
=====================================================================
#undef AF_INET6
#undef PF_INET6
#if !defined(HAVE_GETADDRINFO) || !defined(HAVE_GETNAMEINFO)
#include "getaddrinfo.h"
#endif
=====================================================================
And put getaddrinfo.o to replace/
and patch libraries/clib/net/Makefile.in

That is all. Kaffe can be built on my old Linux machine and runs on it.
(I am not sure that $(top_builddir)/replace/ is the best place to
put getaddrinfo.o.)
