I think this is the essence of your problem. It looks like you are mapping
you temporary directory outside the cygwin directory tree, Not sure how you
are doing it. For me, I have TMP=/tmp and TEMP=/tmp in my cygwin
environment. In my windows environment, i.e, when running cmd.exe, TEMP and
TMP point to C:\Users\Doug\AppData\Local\Temp.

I expect you will find that the windows permissions for your temp directory
is different from the default /tmp.

Check this using lsacl (A bash script found somewhere in this mailing
list.) Or the file properties from windows explorer.

In my case:

$ ls -ld /tmp
drwxrwxrwt+ 1 Admin None 0 May  6 18:51 /tmp/

$ ls -ld $(cygpath -u 'C:\Users\Doug\AppData\Local\Temp' )
drwxrwx---+ 1 Doug SYSTEM 0 May  6 18:50
/cygdrive/c/Users/Doug/AppData/Local/Temp/

$ lsacl /tmp
[u::rwx,g::rwx,o::rwx/u::rwx,g::r-x,o::r-x] /tmp

$ lsacl $(cygpath -u 'C:\Users\Doug\AppData\Local\Temp' )
[u::rwx,g::rwx,g:Administrators:rwx,m::rwx,o::---/u::rwx,g::rwx,g:SYSTEM:rwx,g:Administrators:rwx,m::rwx,o::---]
/cygdrive/c/Users/Doug/AppData/Local/Temp

I suggest you change your temporary directory to ./tmp, or align the
permissions.

HTH,
Doug
