This was inherited from the original FreeBSD infrastructure, and has
never been deleted.

Yes. I suppose no-one has felt the need to do it, that's all.

See: pkgsrc/net/socks4/patches/patch-aa

Basic idea is:

OPSYS!= uname -s

.if ${OPSYS} == "NetBSD"
...
.endif

The above assumes you're using bmake. If you're using gmake, then the syntax
is different:

See pkgsrc/net/rdesktop10/patches/patch-aa

Basic idea is:

OS = $(shell uname -s)

ifeq "$(OS)" "SunOS"
...
endif
