Sorry, you are right.  I added the gethostname module after receiving
this problem report, so this is no longer an issue.

OK, thanks.

|   Depends-on:

|   fcntl-h
| + getdtablesize
|   extensions

|   configure.ac:

I see that this change is checked in now.  Thanks.

| Yes: The linker gave you the file names. For example, in order to know to 
which
| module 'fcntl.c' belongs, you do
| 
|   $ grep -r '^lib/fcntl\.c$' modules
|   modules/fcntl:lib/fcntl.c

OK.

Thanks,
