I am using bash version:
3.1.17(9)

I have tried to use shopt -s igncr but I have an issue with the following shell construct:

t=`gcc --print-multi-lib` where gcc is a mingw gcc.

As my gcc is a mingw program, it outputs CR/LFs. In previous versions bash used to ignore the CR, so t variable was not containing any CR.
Now this is no more the case and this is causing some troubles


Why isn't "t=`gcc --print-multi-lib | d2u`" not a solution here?

Well for two reasons:
- portability. the same homemade scripts are also used among a large flavors of unixes (AIX, IRIX, HP-UX, Tru64, ....). dos2unix is not installed on all of them...


OK. So 'tr' is a better choice then.


What I want to avoid.... will generates a lot of changes that can't be automated :-(



Dan has addressed this in his response so I won't repeat it.

Will try Dan solution with the new version of bash. As I said in my previous mail, if you are interesting in the results I will send them.
