Thanks for that again, being able to ditch filemon on Linux would be
great.

I did a quick smoketest for filemon_dev.c on FreeBSD.
I had to revert some of the changes to Makefile so that filemon_dev compiles;

.if ${USE_FILEMON} == "dev"
FILEMON_H ?= /usr/include/dev/filemon/filemon.h
.if exists(${FILEMON_H}) && ${FILEMON_H:T} == "filemon.h"
COPTS.filemon_dev.c += -DHAVE_FILEMON_H -I${FILEMON_H:H}
.endif
.endif

With the above it seems to work ok, thanks.
