## This file is read several times:
## - once per *extension* (not per language) for generic compilation rules
## - once for each file which requires specific flags.

## Note it is on purpose we wrote `if %AMDEP%', since:
##
## - if deps are turned off, %AMDEP% is mapped onto FALSE, and therefore
##   the `if FALSE' chunk is removed (automake-time conditionals).
##
## - if deps are on, %AMDEP% is mapped onto AMDEP,  and therefore
##   the `if AMDEP' chunk is prefix with @AMDEP_TRUE@ just like for any
##   other configure-time conditional.
##
## 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.  In this case we
## can skip the use of depcomp and easily inline the dependency
## tracking.

## Verbosity of FASTDEP rules
## --------------------------
## (1) Some people want to see what happen 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 line 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.)
