    _______________________________________________________

Details:

Currently,

$(shell false) does not break build:

===
a := $(shell false)

x:
        echo $(a)
===

completes successfully. Should fail, because in scenario:

a := $(shell cat version.txt)

it is hard to catch a situation if version.txt file does not exist.

Seen on gmake 3.81.
