A complete list of bugs fixed in this version is available here:
* New variable: $(.SHELLSTATUS) is set to the exit status of the last != or
$(shell ...) function invoked in this instance of make. This will be "0" if
successful or not "0" if not successful. The variable value is unset if no
!= or $(shell ...) function has been invoked.
* The $(file ...) function can now read from a file with $(file <FILE).
The function is expanded to the contents of the file. The contents are
expanded verbatim except that the final newline, if any, is stripped.
