You misunderstood.  --disable-optimizations has only ever affected the
-O flag, and --disable-debug only the -g flag.  You claimed that using
both together would give -O2, which I simply do not believe; the
string "-O2" does not occur anywhere in configure.

Before my change --disable-optimizations removed the -O flag entirely,
now it sets it to -O1 for icc.  It neither did nor does affect -g, and
--disable-debug neither did nor does affect -O.

If you think any of the above is untrue, please explain _in detail_
why you believe this, so I can fix it.
