> The program's definitions shall not be specified as `inline`.

This seems to permit declarations of replacement allocation functions that are specified as `inline` so long as they aren't used. This behavior seems more like a bug than a feature, I propose that we do the following:

> The program's definitions declarations shall not be specified as `inline`.

Proposed resolution:

This wording is relative to N3797.

1. Modify 16.4.5.6 [replacement.functions]/3 as indicated:

   > -3- The program's definitions are used instead of the default versions supplied by the implementation (18.6). Such replacement occurs prior to program startup (3.2, 3.6). The program's definitions declarations shall not be specified as `inline`. No diagnostic is required.
