-## Verbosity of FASTDEP rules
-## --------------------------
-## (1) Some people want to see what happens during make. They think
-## @-commands are evil because hiding things hinders debugging.
-## (2) Other people want to see only the important commands--those that
-## may produce diagnostics, such as compiler invocations. They
-## do not care about build details such as dependency generation
-## (the if/then/else machinery in FASTDEP rules). Their point is
-## that it is hard to spot diagnostics in a verbose output.
-## (3) Other people want `make -s' to work as expected: silently.
-## This way they can spot any diagnostic really easily.
-##
-## The second point suggests we hide rules with @ and that we `echo'
-## only the relevant parts. However this goes against the two others.
-## There are regular complaints about this on the mailing list, but
-## it's hard to please everybody. On April 2003, William Fulton (from
-## clan (3)) and Karl Berry (from clan (2)) agreed that folding the
-## compile rules so that they are output on a single line (instead of 5)
-## would be a good compromise. Actually we use two lines rather than one,
-## because this way %SOURCE% is always located at the end of the first
-## line and is therefore easier to spot. (We need an extra line when
-## depbase is used.)
+## We do likewise for %FASTDEP%; this expands to an ordinary configure-time
+## conditional. %FASTDEP% is used to speed up the common case of building
+## a package with gcc 3.x or later. In this case we can skip the use of
+## depcomp and easily inline the dependency tracking.
