Strange effects of TZ on su -l

[John H]

Here is a wierdy I came across a while ago.  I have my "TZ" environment
variable set to:

TZ="HFH-1HFE-2;84/2:00,273/2:00"

So I get DST at the right time here in France.  It works very well.

But!  Whenever I do a "su -l" (or any of the sysadm scripts that do
a "su -l" internaly) I get the error:

	00: Invalid identifier

just after I've entered the password.  Does anyone know what might
be going wrong here?

I see the same effect in 386/ix 2.0.2 and Esix System 5.3.2 Rev. C.
