The $FreeBSD$ line is just an indication about the FreeBSD ports committer who happened to commit the changes proposed by the maintainer.] Regarding COSS and AIO: the FreeBSD port sets --enable-coss-aio-opts and requires aio(4) to be loaded if you build Squid with support for UFS, diskd and COSS. If you add AUFS to the mix, COSS will use AUFS provided routines for async io and you do not need to kldload aio to get COSS working. See the section in the port's Makefile starting at line 251 that deals with the SQUID_AUFS option.
