## We used to define this.  However, we don't because vendor makes
## (e.g., Solaris, Irix) won't correctly propagate variables that are
## defined in Makefile.  This particular variable can't be correctly
## defined by configure (at least, not the current configure), so we
## simply avoid defining it to allow the user to use this feature with
## a vendor make.
## DESTDIR =

## Shell code that determines whether we are running under GNU make.
##
## Why the this needs to be so convoluted?
##
## (1) We can't unconditionally use make functions or special variables
##     starting with a dot, as those cause non-GNU implmentations to
##     crash hard.
##
## (2) We can't use $(MAKE_VERSION) here, as it is also defined in some
##     non-GNU make implementations (e.g., FreeBSD make).  But at least
##     BSD make does *not* define the $(CURDIR) variable -- it uses
##     $(.CURDIR) instead.
##
## (3) We can't use $(MAKEFILE_LIST) here, as in some situations it
##     might cause the shell to die with "Arg list too long" (see
##     automake bug#18744).
##
## (4) We can't use $(MAKE_HOST) unconditionally, as it is only
##     defined in GNU make 4.0 or later.
