Re: [PATCH] Makefile: tweak sed invocation

I used to have access to SunOS/Solaris boxes and tried to be careful not to break them unnecessarily, but these days I don't, so I expected to hear quite a huge bit-rotting. I end up building new releases on SunOS all the time; when things break there is usually when you hear from me. I'm hoping this patch makes it into 2.18.1 so I don't have to apply it during my build process. -Alejandro

MacOS and the various BSD's ship with BSD 'sed', not GNU 'sed', so it
seemed prudent to check this change against them as well, which I did,
and can report that it does not cause any regression on those
platforms.
Therefore, the patch looks good. Thanks.
Thanks for checking on that, Eric. I tested MacOS locally before
submitting as well. From a quick skim of the POSIX sed page, the space
is expected, so this should be portable.

[PATCH] Makefile: tweak sed invocation
With GNU sed, the r command doesn't care if a space separates it and
the filename it reads from.
With SunOS sed, the space is required.
