I have not included the files as they are about 40K each, but I have sent
them to Charles.

I still have some unzip & tex from the original 2.03. I have ensured that I
don't haev any 2.04 code. This is why it has taken me so long to get it
right.

100% agree.

It could have been after I tried to build GCC after it allready failed and
therefore I realy screwed up the system.

The strange thing is that I built all of the other exe files that I needed
without a problem, except for the usual installation issues..

I will give this a try.

I have attached a listing of the exe files I have in the updated 2.03 djgpp
directory tree. Files with a data of 01-Jan-2001 were touched before I
started bulding on my  XP PC. The files with the 01/01/01 date are either
original 2.03 files or have been build on my W98 PC. I have also attached
the exe list for the Win 98 PC.

I just "reset" the build.djg directory back to the way it is when you
install GCC 2.9.5.3 an did a build. The following was the last few dozen
lines of stage1.log :-
