Really?  When I run test-netdb under gdb on x86 and set a bkpt on gethostname,
I get the C code.

The test-netdb code is clearly correct according to the description of
gethostname in the manual.  However, the sysdeps/unix/sysv/gethostname.c
code does not behave as the manual says--it should write the truncated name
before returning ENAMETOOLONG.
