1) Fedora Core 6 build fixes

FC 6 does not have /usr/include/linux/sys.h.  The two files in the diff below include it, but I'm not sure why.  If you look at the file on an earlier system, it appears that there is nothing in it.  All it seems to do is define NR_syscalls, which is not used anywhere in any include file that I can find, nor in any ds code.  So I propose changing the code not to include this file.
2) Change version to 1.0.4
I already got the other files, except for ldap/cm/Makefile
