You can define WANT_LIBC_R=yes in /etc/make.conf

I also did some experiments with getting squid 1.2beta15 to compile on
FreeBSD-stable. Indeed some include stuff is missing. I found an extra
pthread_private.h file in /usr/src/lib/libc_r/uthread which contains these
missing things. However just #include'ing it gave some strange errors, so I
made a local pthread_local.h containing just the stuff I needed:

pthread_local.h:

    struct sched_param {
            int sched_priority;
            void *no_data;
    };

    /*
     * Scheduling definitions.
     */
    enum schedparam_policy {
            SCHED_RR,
            SCHED_IO,
            SCHED_FIFO,
            SCHED_OTHER
    };

The following patch was needed to get it to compile:

This makes it compile, but not working yet.

I'm Cc:-ing freebsd-hackers (so be careful with replies), maybe someone
there knows better ways to get Squid 1.2beta to compile with libc_r. I
recently saw some other applications mentioned over there which do work
with libc_r successfully.

There's also work being done on async IO in the FreeBSD kernel (3.0),
haven't tried that yet.
