An update to the preprocessor specification (rev. 2)

by David Krauss

Excerpt:

This proposal updates the preprocessor specification to remove undefined behavior, missing specifications, and possible contradictions, and to better document implementation differences. It resolves CWG DR 268, 366, 897, 1436, 1625, 1698, 1709, 1718, and 1882. Issues related to universal-character-names are not addressed here, but in N4219.
