subst and patsubst

[Joerg Krautwurst-Schmid]

Hello,
 
I have a problem with subst and/or patsubst in gmake.
Imagine the following:
I want to cut of a pice of the current directory to get only a spcific part:
eg.
pwd is /home/jks/playpen/branch_one/xyz/scr/bin
 
now I want to have to root '/home/jks/playpen/branch_one/xyz' without
src/bin.
 
I tried subst and patsubst but this doesn't help.
 
osroot = $(patsubst %xyz%,%xyz, $(CURDIR))
 
OK I can use sed but we have developers on NT which don't have any sed
installed on their machines.
Is there a way to do this, or is it better to give all the non UNIX
developers a copy of sed on NT.
 
Thank for your help
 
Joerg
