 	------ HsCpp opts ---------------------------------------------------
-	-- These options used to put ticks around their arguments for unknown
-	-- reasons. These quotes are stripped by the shell executing system()
-	-- on Unix, but not on Windows, where it therefore goes on to disturb
-	-- gcc. Hence they are now gone; if they need to be replaced later on
-	-- Unix, there will need to be #ifdefery.
+	-- With a C compiler whose system() doesn't use a UNIX shell (i.e.
+	-- mingwin gcc), -D and -U args must *not* be quoted, as the quotes
+	-- will be interpreted as part of the arguments, and not stripped;
+	-- on all other systems, quoting is necessary, to avoid interpretation
+	-- of shell metacharacters in the arguments (e.g. green-card's
+	-- -DBEGIN_GHC_ONLY='}-' trick).
