| ## 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. |
