weird or not, I implemented apr_sendfile() on HP-UX and it works fine
with the APR test program; I'll test with Apache Real Soon Now
(hopefully this weekend); I just got an HP-UX 11 account and need to
get a regression test bootstrapped

(by the way, we don't build with the HP compiler on HP 10.20; need to
look lots further into which compiler I have access to and why it
doesn't like some seemingly benign declarations in APR)

I fixed some and also have an uncommitted patch to add
-D_XOPEN_SOURCE_EXTENDED (forgive spelling mistakes here); I need to
double check the difference in compiler messages with and without
before committing.

Any stress testing you can do with pthread would be great.  I don't
expect to have time to do much more than verify that it basically
works under extremely light loads.  At least this will be done on a
regular basis (thanks to cron and perl).

A few of us at IBM run on AIX 4.3.3 regularly.  AFAIK, any time you
have would be best spent on HP-UX as it would seem to have the least
care and feeding of the two.

certainly!
