[Vm-dev] Make question

Hi Folks -

I'm trying to rework the windows build structure and I'm running into a 
problem with make. Basically, what I'm trying to do is to test whether a 
file exists in a given location and if so, copy it, and if not, copy a 
default from elsewhere. This should look like here:

if $(file-exists locationA/foo.locA)
	cp locationA/foo.locA foo.here
	cp locationB/foo.locB foo.here

I think you get the idea. My problem is that I can't seem to find a 
reliable way of expressing the line

if $(file-exists locationA/foo.locA)

in any reasonable way (i.e., by using make's functions). Any ideas how 
to convince make to determine whether the file exists or not?
