* B20: declare built-in doesn't work in scripts, work around

I am using beta 20.0 under NT 4.0.

Running the following script:

	declare -i count
	count=0
	count=count+1
	count=count+1
	echo count is ${count}

should produce the output:

	count is 2

but instead produces the output:

	declare: not found
	count is count+1

If the above script is in the file "do_it" and I run it from the bash
command line by typing "./doit" I get the wrong output.

If I run it with "source ./doit" it works correctly.

A better work-around to use in general is "( source ./doit )" so that when
the "exit" command appears in the script you are executing, the bash command
shell doesn't disappear.

A bashism.  Isn't supported by sh.

If your here document is #!/bin/sh then you're not executing the script under
bash but under sh and the two aren't the same.  Again, declare is a bashism. 
If your here document is #!/bin/bash then the script will work correctly.

I notice that you have no HOME variable.  Also, you're using the stock b20.1
Cygwin1.dll.  Please read my webpage.
