* WARNING: Backward-incompatibility!
Previously if --no-print-directory was seen anywhere in the environment or
command line it would take precedence over any --print-directory. Now, the
last setting of directory printing options seen will be used, so a command
line such as "--no-print-directory -w" _will_ show directory entry/exits.
* WARNING: Backward-incompatibility!
Previously the order in which makefiles were remade was not explicitly
stated, but it was (roughly) the inverse of the order in which they were
processed by make. In this release, the order in which makefiles are
rebuilt is the same order in which make processed them, and this is defined
to be true in the GNU make manual.
* WARNING: Backward-incompatibility!
Previously only simple (one-letter) options were added to the MAKEFLAGS
variable that was visible while parsing makefiles. Now, all options are
available in MAKEFLAGS. If you want to check MAKEFLAGS for a one-letter
option, expanding "$(firstword -$(MAKEFLAGS))" is a reliable way to return
the set of one-letter options which can be examined via findstring, etc.
* WARNING: Backward-incompatibility!
Previously makefile variables marked as export were not exported to commands
started by the $(shell ...) function. Now, all exported variables are
exported to $(shell ...). If this leads to recursion during expansion, then
for backward-compatibility the value from the original environment is used.
To detect this change search for 'shell-export' in the .FEATURES variable.
* WARNING: New build requirement
GNU make utilizes facilities from GNU Gnulib: Gnulib requires certain C99
features in the C compiler and so these features are required by GNU make:
https://www.gnu.org/software/gnulib/manual/html_node/C99-features-assumed.html
The configure script should verify the compiler has these features.
* New feature: The .WAIT special target
