bug#13040: merge gnulib 'inline' changes

[Paul Eggert]

[-- Attachment #1: Type: text/plain, Size: 276 bytes --]

Tags: patch
Severity: minor

The attached patch brings Emacs up to date with respect to gnulib's
recent 'inline' changes (which were mostly inspired by Emacs).
It touches some Windows-related files so I'm CC:ing this to
Eli to give him a heads-up.  I plan to install it soon.
