TMP and TEMP get redefined, but I need the original values


Hey folks!

I don't update my Cygwin installation regularly, but recently I did, and then a script of mine stopped working.

Looking for the cause I found out that the Cygwin maintainers chose to redefine the TEMP and TMP environment variables in /etc/profile like this:

unset TMP TEMP
TMP="/tmp"
TEMP="/tmp"

http://cygwin.com/ml/cygwin/2011-03/msg00211.html

Before that change, the TMP and TEMP defined by Windows were used unmodified (except for cygpath translation). I'm sure the maintainers have good reasons for this change. However, now I'm unable to find out the original TEMP setting from a script.

To help your imagination what this could be good for, the purpose of the script in question is for aiding in Windows maintenance, specifically for cleaning up the TEMP folder.

I helped myself by deactivating the lines cited above in /etc/profile for now, but that is clearly not a fine solution. Well, I could store the original values of TMP and TEMP in backup variables, like WINDOWS_TEMP or so. That would have to go in /etc/profile before the variables are unset. But then, this modification would probably get overwritten the next time something is changed in that file on the distribution side. (If it would not, I wouldn't have had the problem in the first place.)

So, any ideas how this could be solved in a clean way?
