I am trying to rebuild my system with LTO enabled gcc.

Compilation of Gentoo package /net-nds/openldap-2.4.38-r1 ended with:

Coul you kindly please look into it? I think that header(s) can be missing in
source files and library(ies) at link time.

I uploaded david-kredba-20131213-build.log and david-kredba-20131213-config.log
to your ftp server.

Thank you in advance.
