All,

The attach patch maps REAL128 from iso_fortran_env to
the REAL kind type with widest precision.  Prior to
this patch, REAL128 is mapped to the first REAL kind
type with a matching storage size of 128 bits.  On
x86_64-*-freebsd both REAL(10) and REAL(16) occupy
16 bytes, but REAL(10) is mapped to REAL128.  This
may surprise users that assume REAL128 is mapped to
an IEEE754-2008 128-bit floating point entity with
113 bits of precision.  OK to commit?

Yes, thanks.

Mikael
