I think both patches are not ok.

1.patch:
 - ALWAYS include replace.h or includes.h as first header
   otherwise we'll break older systems.
 - I think we should try to not include uid_wrapper.h in heimdal_build/
 - And also not in includes/includes.h
 - I think we should only include it in source4/ntvfs/unixid/ and
   lib/util/unix_privs.c (if it doesn't break make test).
   And then #include "system/passwd.h" should be included in both
   C files instead of in uid_wrapper.h

2.patch:
 - I think the nsstest part is ok
 - The heimdal part needs to be fixed by defining NSS_WRAPPER_DISABLE
   in heimdal_build/roken.h, we nees NSS_WRAPPER_DISABLE in the same
   way we have SOCKET_WRAPPER_DISABLE
