$(eval): >193 chars on a line yields ' virtual memory exhausted'

[gk]

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

address@hidden 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.)
