INSTALL now suggests VPATH builds (e.g., "sh ../srcdir/configure")
only if you use GNU make. In practice, other 'make' implementations
have too many subtle incompatibilities in their support for VPATH.
These incompatibilities do not hurt bare Autoconf, but do affect
Automake-generated makefiles. Recommending GNU make keeps the
installation instructions simpler.
Many packages (including Autoconf itself) are portable to other
'make' implementations, but some packages are not, and recommending
GNU make keeps the installation instructions simpler.
** Even more safety checks for the new Directory variables:
Warn about suspicious `${datarootdir}' found in config files output.
