I followed the steps in the user manual as follows:

a) Extract UnxUtils.zip to your C:\ hard disk PRESERVING the original paths, otherwise bison won’t work.
(If you are using WinZip make certain that ’Use folder names’ is selected)
b) In the Visual C++ IDE click Tools, Options, select the Directory tab, in ’Show directories for:’ select
’Executable files’, and in the directories window add a new path: ’C:\user\local\wbin’, click ok.
(As a side effect, you get a bunch of Unix utilities that could be useful, such as diff and patch.)

The instructions go on to say: Open ’sdcc.dsw’.  The problem is, I cant find the folder in which this file is located.  Can someone please tell me where I would find this file?

Kevin
