special environment variables set by bash

[Helmut Dipper]

Hello,

my bash version is 2.05.0(6), it is executed
under use of the cygwin1.dll on Windows-XP

Problem:
Immediately after starting the bash environment
variables exist with following names
'!::', '!?:' and '!D:'. These variables do not
exist prior to the start of the bash.

A program (e.g. nant) started in this environment
tries to construct 'property names' of the format
'sys.env.<variable>' and fails because the names
mentioned above lead to invalid names.

The bash-builtin 'unset' doesn't accept those
variable names.

How can the creation of these variables be avoided
or how can they be unset?

Best regards
Helmut Dipper
