N2211 described changes in C11 and TS 18661 to remove references to
DECIMAL_DIG, which CR501 is expected to obsolesce. The changes that apply to
C11 are collected in N2253 as an update to the suggested TC in CR501. The
changes that apply to TS 18661-1 are in the CR in N2254. The remaining change is
for TS 18661-3, which is covered by the CR in this document.
At the end of clause 7, omit:
With the following change,

Apr 2018 meeting
The paper was only briefly discussed.
This resolution is tied to the Floating Point CR 20 as well as to the C2x DR 501.
Oct 2018 meeting
A new paper N2255 was split out from N2211 that incorporates directly the Suggested Technical Corrigendum already extracted above.
The committee accepts the Suggested Technical Corrigendum as the Proposed Change to resolve this issue.
