Samba v4.3.8 Build Error Related to com_err.h

Hi,

I'm seeing the following build error during my cross-build of Samba v4.3.8. These builds have previously been working fine for me. However, I've recently updated several (seemingly) independent packages (including Python, from v2.7.3 to v2.7.11) and I'm wondering whether this has had some effect. 

Here's the build error with some verbose output:

	./buildtools/bin/waf -j 1 -v build

Furthermore, I see that the version of com_err.h in .../rfs/user/include matches the version that's part of my Kerberos v1.4.1 installation. This file does not match the Heimdal version (present in the samba ./source4/heimdal/lib/com_err directory). Which version of this file should the build be using? I see that USING_SYSTEM_COM_ERR is set to '1' in bin/default/include/config.h so it seems like the .../rfs/usr/include/com_err.h reference/dependency is correct? 

Considering all of this I see that I can correct this build failure with a change to ./source4/heimdal/lib/krb5/krb5.h as follows:

diff -Naur orig/source4/heimdal/lib/krb5/krb5.h new/source4/heimdal/lib/krb5/krb5.h

 /* simple constants */

I see that the tip of this file in the repo indicates this file hasn't changed for years (all v4 versions are identical). Does the above change make sense generally?

Cheers,
