  Hi,

     I wish I could claim that it was a typo, but no;
  "I was confused".  Yesterday I reported on "Wrong math
  results", quoting several examples similar to:

./xgcc -o March-21 -B./ -O2 -march=i586 March-21.c -lm

  Of course, I should have used -mcpu=i586 or -mpentium or
  -m486, and so on.

  Strange thing is, it makes no difference; the errors remain
  unchanged !!

  Sorry, if I caused any confusion.

  Roger B.
