Details:

Apologies for the windows stuff but the following makefile clean target does
not work:

all: $(filter-out $(wildcard build\release), build\release)

build\release:
        mkdir build\release

clean:
        rmdir /Q /S build

First do gmake all then try gmake clean. The following error occurs:

rmdir /Q /S build
The process cannot access the file because it is being used by another
process.
gmake: *** [clean] Error 32

I have managed to trace the cause to the fact that the wildcard function
opens a handle to the build directory in order to check if the release
directory exists and then does not release the handle till gmake exits
