Hi Eric,
On HP-UX 11, I got these test failures:
test-ftell.c:85: assertion failed
./test-ftell.sh[3]: 9644 Abort
FAIL: test-ftell.sh
test-ftello.c:93: assertion failed
./test-ftello.sh[3]: 9648 Abort
FAIL: test-ftello.sh
In fact, when reading from a regular file, after the fseek, the file position
is 120 instead of 3. Since none of ftell, fseek, ungetc are overridden by glibc,
this looks like a HP-UX bug to me.
I'm categorizing it as "known bug", and disabling this part of the tests.

Work around a HP-UX stdio bug.
* tests/test-ftell.c (main): Disable the fseek/ftell test on HP-UX.
* tests/test-ftello.c (main): Likewise.
* doc/posix-functions/ftell.texi: Mention HP-UX bug.
* doc/posix-functions/ftello.texi: Likewise.
