Re: Compile squid1.2beta15 with async-io

 It is about a week since a looked at this but when I did I found
that squid expected

pthread_attr_setscope pthread_attr_setschedparam and pthread_setschedparam

 These are not currently implimented in FreeBSD-current's libc_r as
it is not possible to set a scheduling policy.[1]

 In addition the code also currently depends on a number of things defined
in or included from Solaris pthread.h which may not be in the same place
or defined at all elsewhere:

Particularly:

The sched_priority member of the structure sched_param.

struct sched_param{
        int sched_priority;
        }

May suffice, I defined the whole structue. See /usr/include/sched.h on a
Solaris box.

Also

#define SCHED_OTHER 0

is also required, allthough there is an obvios workaround to this :-).

The above allowed me to compile under IRIX 6.2 although I have yet to test
the binary.

Removing the scheduling stuff (Yes I Know, Duh!) Allowed me to compile under
FreeBSD current, however I got a segmentation fault after about 30 seconds
of moderate load. Hardly unexpected really.
