Linking systemd-analyze fails with:
error: undefined reference to 'config_parse_warn_compat'

That's because config_parse_warn_compat() is compiled in only if one of these defines is not defined:

#if !defined(HAVE_SYSV_COMPAT) || !defined(HAVE_SECCOMP) || !defined(HAVE_PAM) || !defined(HAVE_SELINUX) || !defined(HAVE_SMACK) || !defined(HAVE_APPARMOR)
int config_parse_warn_compat(

Unfortunately in my case I have all these defined.

Yet src/core/load-fragment-gperf.c wants config_parse_warn_compat unconditionally.

Solution - dropping these guard defines and always compiling config_parse_warn_compat in.
