I attached a Makefile and t.cpp. Put these into a directory which has a space
in its name. Run make, notice that it works correctly.

Now, at line 14, change the order-only dependency to "| $$(ROOT)/build" (add a
$ in front). Delete the "build" directory, and try again make. This time make
will fail a "No rule to make target '<path>/sp bug/build/t.o' message.

If I use the -d switch to make, I see this:


Considering target file 'all'.
 File 'all' does not exist.
 Looking for an implicit rule for 'all'.
 No implicit rule found for 'all'.
  Considering target file '<path>/sp bug/build/t.o'.
   File '<path>/sp bug/build/t.o' does not exist.
   Looking for an implicit rule for '<path>/sp bug/build/t.o'.
   Trying pattern rule with stem 't'.
   Trying implicit prerequisite '<path>/sp\'.
   Trying pattern rule with stem 't'.
   Trying implicit prerequisite '<path>/sp\'.
   Looking for a rule with intermediate file '<path>/sp\'.
    Avoiding implicit rule recursion.
   No implicit rule found for '<path>/sp bug/build/t.o'.
   Finished prerequisites of target file '<path>/sp bug/build/t.o'.
  Must remake target '<path>/sp bug/build/t.o'.
make: *** No rule to make target '<path>/sp bug/build/t.o', needed by 'all'. 
Stop.


It seems that even though "sp\ bug" has the space escaped, it is still split
into two parts, "sp\" and "bug".
