20 ## This file is read several times:
21 ## - once per *extension* (not per language) for generic compilation rules
22 ## - once for each file which requires specific flags.
24 ## Note it is on purpose we wrote `if %AMDEP%', since:
26 ## - if deps are turned off, %AMDEP% is mapped onto FALSE, and therefore
27 ## the `if FALSE' chunk is removed (automake-time conditionals).
29 ## - if deps are on, %AMDEP% is mapped onto AMDEP, and therefore
30 ## the `if AMDEP' chunk is prefix with @AMDEP_TRUE@ just like for any
31 ## other configure-time conditional.
33 ## We do likewise for %FASTDEP%; this expands to an ordinary
34 ## configure-time conditional. %FASTDEP% is used to speed up the
35 ## common case of building a package with gcc 3.x. In this case we
36 ## can skip the use of depcomp and easily inline the dependency
39 ## Verbosity of FASTDEP rules
40 ## --------------------------
41 ## (1) Some people want to see what happens during make. They think
42 ## @-commands are evil because hiding things hinders debugging.
43 ## (2) Other people want to see only the important commands--those that
44 ## may produce diagnostics, such as compiler invocations. They
45 ## do not care about build details such as dependency generation
46 ## (the if/then/else machinery in FASTDEP rules). Their point is
47 ## that it is hard to spot diagnostics in a verbose output.
48 ## (3) Other people want `make -s' to work as expected: silently.
49 ## This way they can spot any diagnostic really easily.
51 ## The second point suggests we hide rules with @ and that we `echo'
52 ## only the relevant parts. However this goes against the two others.
53 ## There are regular complaints about this on the mailing list, but
54 ## it's hard to please everybody. On April 2003, William Fulton (from
55 ## clan (3)) and Karl Berry (from clan (2)) agreed that folding the
56 ## compile rules so that they are output on a single line (instead of 5)
57 ## would be a good compromise. Actually we use two lines rather than one,
58 ## because this way %SOURCE% is always located at the end of the first
59 ## line and is therefore easier to spot. (We need an extra line when
