Re: [PATCH v2 2/2] PRU: Align libmath to PRU ABI

[Joel Sherrill <joel at rtems dot org>]

There has been a general trend in the BSD world to go to 2 paragraph. 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.
