>I am hoping some people can give me ideas on how to debug a problem I am having with rm when invoked from cygwin's make.exe, which is using sh as its shell. Basically, when I call "rm -r -f" from a makefile, it gives me errors about "Permission Denied, Directory Not Empty". This is the same error that I get when I try to manually rm a directory when I have a separate shell cd'd there. I think that somehow make or sh are cd'ed into the directory I am trying to rm, so it cannot be removed.

I have tried replacing rm and the cygwin1.dll with different versions, but I get the same error. I also tried replacing sh with bash, same error. I plan on trying different versions of make and sh, but if anyone can suggest what to strace or which files I can plug printfs into, I would really appreciate it.


Have you tried creating the smallest makefile that will reproduce the problem 
and then running that under strace?  Make sure nothing else (not even a 
Windows process) has the directory open.
