include file configuration

[andreas moroder]

Hello,

would it be possible to change includes.h the way that #include <syslog.h> is 
included only if --with-syslog whas choosen in the configuration.

Could the same be done with nsswitch/nss.h and --with-winbind?

This would have two advantages:

1. Faster compilation ( noticeable ? )

2. splint works ( it does not like a line in syslog.h )

Bye

Andreas
