But a lot of existing code hasn't been updated to it. Sometimes the original author can't be found to ask. In newlib's case, the target end user is embedded systems and it is just another odd thing to keep up with for them to be compliant. Hopefully we can do an audit and remove the paragraph where it has been removed.upstream. On Mon, Aug 26, 2019, 3:08 PM Dimitar Dimitrov wrote: > There is no particular reason.
