OK, it was just a suggestion. Minor point. Just wanted the configure to
get it right in one more case. As I said, some packages configure and get
this right. Why not autoconf?
What about something like if or case to check
# Check for NEC SX compiler
if cc -c -V 2>&1 | grep '/SX' > /dev/null 2>&1 ; then
# action for NEC
else
# all the rest
fi
NOTE: - it was NEC SX-5 cc, not Cray.
Problem 2: This time for Cray.

I agree it's sort of recursive, trying to make configure portable so that
it will configure some other package portably. I still think the suggestion
is reasonable - use $SED not sed wherever possible, with some sensible default
${SED-sed}? which allows an override by those in trouble and in the know, and
no change for anyone else.
