更新内容：
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
The function is expanded to the contents of the file. The contents are
expanded verbatim except that the final newline, if any, is stripped.
The makefile line numbers shown by GNU make now point directly to the specific line in the recipe where the failure or warning occurred.
Sample changes suggested by Brian Vandenberg
The interface to GNU make's "jobserver" is stable as documented in the manual, for tools which may want to access it.
WARNING: Backward-incompatibility! The internal-only command line option--jobserver-fds has been renamed for publishing, to --jobserver-auth.
The amount of parallelism can be determined by querying MAKEFLAGS, even when
the job server is enabled (previously MAKEFLAGS would always contain only
"-j", with no number, when job server was enabled).
VMS-specific 更新:
Perl test harness now works.
Full support for converting Unix exit status codes to VMS exit status
codes. BACKWARD INCOMPATIBILITY Notice: On a child failure the VMS exit code is now the encoded Unix exit status that Make usually generates, not the VMS exit status of the child.
