Every GCC language testsuite has these failures, I just singled out
Fortran because I was interested in it.

Setting TERM doesn't help.  Wine tries to emulate the windows console,
which requires outputting this stuff.  It does so any time there's a
pty, and I believe that Deja creates a pty when running the tests.
Wine people suggested if I could somehow run the test as "wine ./a.exe
| cat", that it would prevent this behavior, but I couldn't find a way
to do that.  For now, I modified Wine to kludge out the code that
creates the console, and a long term solution needs to be on the Wine
side.  I was just hoping for a less dirty hack from the Deja side.

Note that there are other problems, too.  It seems that when Deja is
matching against "\n", it doesn't handle the different line endings of
Windows correctly in a cross environment.  Is there a way that I can
set how to interpret \n in a target-board file?  This affects fortran
and other language tests also.
