I originally had several short prerequisites on the line but discovered
that it doesn't matter how you break up the characters (spaces don't seem
to have any affect though).
# makefile
define foo
a:12345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901
@echo 'hi'
endef
$(eval $(call foo))
# eof
[greg@p3 junk]$ make
make: *** virtual memory exhausted. Stop.
If you remove one character, anywhere on the long line, the error goes away
and a normal message results:
make: *** No rule to make target
`1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890',
needed by `a'. Stop.
(Adding a rule to make the target has no effect.)
