Thanks, but... 

No offense, but this is not overly helpful.  The problem is to learn
*why* this happens and how to fix it.  For that I'd need to know what
your permissions on /tmp look like (ls -l, getfacl, icacls).  Creating
files in my /tmp (having an old-style ACL) with the following
permissions works as desired for me:

  $ uname -rm
  2.0.0(0.287/5/3) x86_64
  $ ls -ld /tmp
  drwxrwxrwt+ 1 corinna vinschen 0 Apr 12 10:25 /tmp
  $ getfacl /tmp
  # file: /tmp
  # owner: corinna
  # group: vinschen
  # flags: --t
  user::rwx
  group::rwx
  mask:rwx
  other:rwx
  default:user::rwx
  default:group::r-x
  default:mask:r-x
  default:other:r-x

  $ icacls C:\\cygwin64\\tmp
  C:\cygwin64\tmp VINSCHEN\corinna:(F)
		  VINSCHEN\vinschen:(RX,W)
		  Everyone:(RX,W)
		  NULL SID:(RD)
		  CREATOR OWNER:(OI)(CI)(IO)(F)
		  CREATOR GROUP:(OI)(CI)(IO)(RX)
		  Everyone:(OI)(CI)(IO)(RX)
