Re: Help fixing NativeMessaging host: read 32-bit message length in native byte order

[guest271314]

  length=$(dd iflag=fullblock bs=4 count=1 | od -An -td4)
  IFS= read -rN"$length" message

works.

What else in the code is GNU-specific?

Let's make sure we create a true non-GNU version now. What do we call it?
