This indeed solves the problem and thanks for explaining the default 
shell issue. I actually thought that bash was used under cygwin, and I 
often construct syntax in a bash shell before using it in a makefile. It 
usually works but you've pointed out why there will be subtle differences.

BTW the example I sent was obviously a cut down to illustrate the 
problem. I actually construct  a variable that points to the root 
directory of the checked out CVS view (or a default an environment 
variable if that directory is not under CVS yet), that  enables me to 
specify the "absolute path" to my scripts (or other) directories.  Like 
this:


CVSVIEW    = $(shell if [ -e CVS/Repository ]; then echo ${CURDIR} | sed 
-e "s|`cat CVS/Repository | sed -e "s|^[^/]*||"`||"; else echo 
$$CVSVIEW; fi)

bus_pack-pkg.vhd : ${CVSVIEW}/doc/mem_map.csv ${CVSVIEW}/etc/bus_pack.pl
    perl ${CVSVIEW}/etc/bus_pack.pl -v ${CVSVIEW}/doc/mem_map.csv 
bus_pack-pkg.vhd


Even though it now working, is there a better way of doing this?
