Is there any reason that the Sun Studio compiler still gets called with

The other reason is practical: though running debug bits will help us
catch more bugs sooner, fewer people will do it if they have to run
unoptimized binaries. There's already a performance penalty for
running debug bits, and adding another (and probably much larger one)
isn't going to win friends.
Ok... but sometimes it may be "nice" to have a non-optimized binary...
... would it be possible/usefull to add something like a "-D" switch to
"bldenv" which turns debugging "on" and the optimizer "off" (or uses
-"xO0", assuming dbx doesn't switch to it's "restricted" mode in this
case) ?

Project teams sometimes leave alternate targets in place for these
types of builds. This allows them to debug quickly.
