The directory, 'di4', found by directory search algorithm, is not
considered for 'di2/preq2' of the rule, 'all5'. The steps to reproduce
the result has been written as three steps:
1) makefile9:
-
vpath preq1 di4
vpath di2/preq2 di3
all5: preq1

intermediate file?
.INTERMEDIATE: my.gch
%.all: %.gch
@echo hh

@echo
@touch $@
