I have not been able to reproduce this; it seems to Just Work[TM].

The syscall header stuff is definitely not to blame: it doesn't even 
*see* the CONFIG_ settings; instead they are only used to determine 
which subset of files to create, but the files themselves are 
configuration-independent.  This is by design.

As such, without an actual known to fail test case there isn't much I 
can do.
