## On Intel (and Intel-like) systems using extended-precision registers

## double rounding errors, the test below involving strtodt generally shows

# xQtest generates cp commands that depend on sizeof(long double).
# See the source for details.  If you know better, create Q.out,
# x.out and xL.out by copying the relevant *.ou0 or *.ou1 files
# to the corresponding .out files.  In short, the *.ou0 files are
# for long double == double; x.ou1 and xL.ou1 are for
# long double == extended (a la 80x87 and MC680x0), and Q.ou1 is
# for long double == quad.
