It may help to state the *specific meaning* of ENV in POSIX shells. I looked at the man page for bash and it says:

"When invoked as an interactive shell with the name sh, bash looks for the variable ENV, expands its value if it is defined, and uses the expanded value as the name of a file to read and execute."

So I can imagine a call to "$ENV sh something" in a makefile to explode. What actually happened?
