My reading is that there *is* checking by default, but it is turned
off if you have a subdir configure, but then can be turned back on
again by the user.
Good eye, Tom. The only problem here is my configure.ac doesn't use a
AC_CONFIG_SUBDIRS because there are no child configure.ac scripts to
run, so by default that checking should have been enabled. It's
possible I could be doing something wrong though.
A project can be made subordinate to another project without the
author of the subordinate project being aware of it. This is a very
useful capability. This capability is used by projects such as GCC.
The Autotools philosophy is to provide as much freedom as possible to
the end user while working in a consistent way. This would include
the case where a project is created which builds several other
projects.
