Apparently the regression test is comparing the results/float8.out
with expected/float8-small-is-zero.out  because of the following line
in
src/test/regress/resultmap :
   float8/i.86-pc-cygwin=float8-small-is-zero

I've changed that line to :
    float8/i.86-pc-cygwin=float8
and the regression test ended successfully :   "All 100 tests passed."

I don't know why there are several expected results for the float8 test,
depending on the platform. Is the modification ok?

I've attached the patch,  and  cc'ed   to pgsql-patches.
