By extending the set of floating types, TS 18661-3 thereby affected
the definition of DECIMAL_DIG, which is defined in terms of the
"widest supported floating type". This is not conditional on whether
__STDC_WANT_IEC_60559_TYPES_EXT__ is defined when <float.h> is
included.
I raised this possible incompatibility with C11 (an implementation
should be able to conform simultaneously with C11, and with C11 + TS
18661) in DR#501. This is not yet resolved, but the latest proposal
<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2108.pdf> would
obsolete DECIMAL_DIG with the intention of limiting it to the C11
types (so making it equivalent to LDBL_DECIMAL_DIG). (This proposal
is intended to go along with a corresponding change to TS 18661-3 to
avoid the new types and non-arithmetic interchange encodings affecting
the value of DECIMAL_DIG.)
To avoid releasing GCC 7 with a wider-than-C11 value of DECIMAL_DIG
and possibly reverting back to a C11 value in a future release, this
patch reverts back to the C11 value now. If the proposed resolution
to DR#501 changes again so that DECIMAL_DIG *should* have a
wider-than-C11 value, we can move back to a wider-than-C11 value in
GCC 8.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.
