+ * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
+
* doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
typically overflows on x86 CPUs, even though the C standard
requires otherwise.
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.
