Hi Eric,

I removed everything and completely re-installed Cygwin with setup.exe using the UNIX
binary option.  I 'set -o igncr' in .bashrc.  'set | grep SHELLOPTS' show igncr is set.
Yet the problems of bash scripts failing with '\r' errors and the resultant .CSV has
a '^M' added to each line still appear.  So it's going to take more than just installing
using a binary setup and setting igncr in bash to resolve the problems.

I ran D2U on each bash script AND on the data files that it grep-ped within the
scripts.  Voila! Problem solved.  Each script and data file came from a WinME system
that had an aging version of cygwin (circa mid-2005).  I wrote a script to run every
file through d2u.  Interestingly that script had to be 'd2u-ed' first.

So I have a solution but I fail to see why the binary setup and igncr didn't work.
I don't want to run every file I bring over through d2u as it's laborious.

In a unrelated problem, the diff command doesn't seem to be in the installation.
It was missing the last time I installed cygwin-1.5.24.
