PR:

Two things: replaced the use of spawn_child with ap_spawn_child_err_buff
in various modules (to be "safe" under Win32) and modified the agent and
referer logging modules to use ap_open_piped_logs rather than try and do
it on their own.

I'm not sure that uncompress_child in mod_mime_magic is correct; could
someone look at it?

Also, Ralf, mod_rewrite.c needs similar treatment.  I was off to do it but
it looked more complex than the other changes, and I'm sure once you see
the changes made here you can understand which mod_rewrite changes to make.
