Follow-up Comment #24, bug #48643 (project make):
If we decide to do this I'm not sure it should be a command line flag: command
line flags should be limited to modifying how a given user wants their build
to run. It shouldn't modify fundamental ways that a makefile is parsed.

Thanks for your though
Greetings!
I get unexpected behavior with the following toy makefile when *d_file*

|| echo "making b_file from $<" > b_file||
|| echo "making c_file from $<" > c_file||

Sure, any suggestions are welcome, if someone knows how to do it, can use my

This has been stated twice as an absolute fact but it leaves an obvious
question: why can't GNU make dig up these special "=" env vars on its own
and add them to its custom "envp" env

because Make invokes programs asynchronously, i.e. it doesn't wait for the
child to exit, and so modifying Make's environment will affect Make itself

Follow-up Comment #7, bug #61409 (project make):
It is unrealistic to ask Make not to modify the environment of the programs it
invokes, because some of the GNU Make features absolutely require to put stuff
into the child environment. Your suggestion to modify the Make's own
environment also won'

Yet another option is to have compatibility search disabled by default and
introduce flag '--enable-compatibility-search'.
This is a good choice going forward, because we really don't want new
makefiles to rely on compatibility search.
This choice
