Discussion:
After acceptance ofP0941R2 into the working draft, in [support.limits.general],__cpp_lib_to_chars is required to be in<utility>. Since the relevant feature (std::to_chars andstd::from_chars) is now in the header<charconv>, should the macro be defined in<charconv> instead of<utility>?
[Marshall provides P/R and context]
std::to_chars, etc were originally proposed for the header<utility>and SD-6 reflected that. Somewhere along the way, they was put into their own header<charconv>, but the document was never updated to reflect that.
When these macros were added to the standard, the (now incorrect) value was copied as well.

Proposed resolution:
This wording is relative to (the Rapperswil post-mailing standard).
Change 17.3.1[support.limits.general] (Table 35) as indicated:
| Macro name | Value | Header(s) |
|---|---|---|
__cpp_lib_to_chars | 201611L | <charconv |
