dlltool emits extraneous CRs when using def file with CRLF endings

[Yitzchak Scott-Thoennes <sthoenna at efn dot org>]

For some reason, when I run dlltool using a def file with CRLF line
endings, it is outputing CRs to stdout.  Is there a reason for this?
It's breaking some automated test scripts for me.

$ od foo.def
000000 45 58 50 4f 52 54 53 0a 20 20 66 6f 6f 0a 20 20  >EXPORTS.  foo.  <
000010 5f 66 6f 6f 20 3d 20 66 6f 6f 0a 20 20 0a        >_foo = foo.  .<
00001e

$ !dll
dlltool --input-def foo.def --output-exp foo.exp|od
000000

$ u2d foo.def
foo.def: done.

$ dlltool --input-def foo.def --output-exp foo.exp|od
000000 0d 0d 0d 0d                                      >....<
000004

$ alias od
alias od='od -A x -v -t x1z'
