> Automake 1.14 is warning us about upcoming 2.0 making subdir-objects mandatory.
> This is a feature that has been around for many years but never used in X.
> This feature is not compatible with the way our makefiles cherry-pick source
> files from other directories anywhere in the source tree.
> 
> The subdir-objects feature assumes the path for the source code specified
> in _SOURCES represents a subdirectory relative to makefile. Dependency tracking
> uses the path verbatim to create a directory such as '$(top_srcdir)/hw/xfree86'
> without resolving the variable. The object code will not be generated where
> the makefile is, but in the same where the source was specified.

Ugh, please no.  Can't we just stick to automake 1.x?

>From a practical point of view, some of us import Xorg into other
version control systems that don't properly support symlinks.
