Erm... it should simply work (and not crash).

One RFE would be a message system when/if the compiler does any
optimisations (and which one). I strongly miss the (Amiga) SAS/C feature
which was announcing informations like (you already have something like
this for loop paralisation (e.g. -xloopinfo)):
- Variable removed
- Variable datatype changed (e.g. local |int| reduced to |bool| when
only { 0, 1 } were used as value (and no pointer to this variable was
used))
- Code block removed, moved etc.
- Function inlined
- Function declared inline but not inlined
- Loop unrolled
<...and so on...>
Such a system could greatly help finding bugs in the optimizer or at
least guess what the compiler was doing...
2nd RFE: Enable "-xcsi" by default (and provide an option "-xnocsi" to
turn it off). The compiler should be CSI-conformant by _default_ (note:
This does _not_ mean localisation (= l10n), I am talking about multibyte
characters in the source code) and not optionally. gcc supports this
since _years_ and it's one of the "sour points" for non-english speaking
users like the japanese/chinese developer communities (it's not even
well known that Sun Studio acutally support this... ;-( ).

Well... a scriptable interface would be nice (e.g. something which
doesn't require a X11 connection).
