Details:

Here is a simple makefile to reproduce the bug:


#       invoke this makefile with parallel jobs:
#       make -j8 all
#       1. the my-main-rule rule has a dependency on the dummyfolder
#       2. the dummyfolder is created during pre-build step
#       3. pre-build rule is a prerequisite for the my-main-rule which means
#               my-main-rule executes only if pre-build step finished
#       
#       It fails to execute make -j8 all:
#       mingw32-make: *** No rule to make target `dummyfolder', needed by
`my-main-rule'.  Stop.
#       mingw32-make: *** Waiting for unfinished jobs....
#       '     Before executing PRE BUILD step '
#       mkdir dummyfolder
#       '     After executing PRE BUILD step '

all: main-build

main-build: pre-build my-main-rule 

# Tool invocations
my-main-rule: dummyfolder | pre-build
        @echo 'Building target'

pre-build:
        address@hidden '     Before executing PRE BUILD step '
        -mkdir dummyfolder
        address@hidden '     After executing PRE BUILD step '
