I am unfamiliar with .in - is this supposed to be converted into a .cs by someone/thing, or is this simply the .cs with some extra crud at the end of the name?

A `.in` file is an "input" file, often processed by sed, to replace various strings within the file.

In the case of Consts.cs.in, the string to be replaced is @MONO_VERSION@, which is done by mono/mcs/build/Makefile [0]

	common/Consts.cs: common/Consts.cs.in $(wildcard config.make)
		test -n '$(MONO_VERSION)'
		sed -e 's,@''MONO_VERSION@,$(MONO_VERSION),' $< > $@
