I am using bash version:

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.
- these constructs are appearing in projects like GCC (I triggered the
error while building a mingw GCC).
Which is why I suggested doing the translation so you don't get caught.
Is there any technical reason why igncr does not handle this case ?
What's the exact semantic of this option by the way ?
Dan has addressed this in his response so I won't repeat it.
