-dnl GST_CHECK_FEATURE(FEATURE-NAME, FEATURE-DESCRIPTION,
-dnl DEPENDENT-PLUGINS, TEST-FOR-FEATURE,
-dnl DISABLE-BY-DEFAULT, ACTION-IF-USE, ACTION-IF-NOTUSE)
-dnl
-dnl This macro adds a command line argument to enable the user to enable
-dnl or disable a feature, and if the feature is enabled, performs a supplied
-dnl test to check if the feature is available.
-dnl
-dnl The test should define HAVE_<FEATURE-NAME> to "yes" or "no" depending
-dnl on whether the feature is available.
-dnl
-dnl The macro will set USE_<FEATURE-NAME> to "yes" or "no" depending on
-dnl whether the feature is to be used.
-dnl Thomas changed this, so that when USE_<FEATURE-NAME> was already set
-dnl to no, then it stays that way.
-dnl
-dnl The macro will call AM_CONDITIONAL(USE_<<FEATURE-NAME>, ...) to allow
-dnl the feature to control what is built in Makefile.ams. If you want
-dnl additional actions resulting from the test, you can add them with the
-dnl ACTION-IF-USE and ACTION-IF-NOTUSE parameters.
-dnl
-dnl FEATURE-NAME is the name of the feature, and should be in
-dnl purely upper case characters.
-dnl FEATURE-DESCRIPTION is used to describe the feature in help text for
-dnl the command line argument.
-dnl DEPENDENT-PLUGINS lists any plugins which depend on this feature.
-dnl TEST-FOR-FEATURE is a test which sets HAVE_<FEATURE-NAME> to "yes"
-dnl or "no" depending on whether the feature is
-dnl available.
-dnl DISABLE-BY-DEFAULT if "disabled", the feature is disabled by default,
-dnl if any other value, the feature is enabled by default.
-dnl ACTION-IF-USE any extra actions to perform if the feature is to be
-dnl used.
-dnl ACTION-IF-NOTUSE any extra actions to perform if the feature is not to
-dnl be used.

-dnl # this exists because of shortsightedness on the POSIX committee.
-dnl # BSD systems used "int *" as the parameter to accept(2),
-dnl # getsockname(2), getpeername(2) et al. Consequently many Unix
-dnl # flavors took an "int *" for that parameter. The POSIX committee
-dnl # decided that "int" was just too generic and had to be replaced
-dnl # with "size_t" almost everywhere. There's no problem with that
-dnl # when you're passing by value. But when you're passing by
-dnl # reference (as it is the case for accept(2) and friends) this
-dnl # creates a gross source incompatibility with existing programs.
-dnl # On 32-bit architectures it creates only a warning. On 64-bit
-dnl # architectures it creates broken code -- because "int *" is a
-dnl # pointer to a 64-bit quantity and "size_t *" is usually a pointer
-dnl # to a 32-bit quantity. Some Unix flavors adopted "size_t *" for
-dnl # the sake of POSIX compliance. Others ignored it because it was
-dnl # such a broken interface. Chaos ensued. POSIX finally woke up
-dnl # and decided that it was wrong and created a new type socklen_t.
-dnl # The only useful value for socklen_t is "int", and that's how
-dnl # everyone who has a clue implements it. It is almost always the
-dnl # case that this type should be defined to be an "int", unless the
-dnl # system being compiled for was created in the window of POSIX
-dnl # madness.
