#817: inconsistency between -O5 and -optimize-level 5 in csc
---------------------+------------------------------------------------------

     Type:  defect   |      Status:  new  
 Priority:  minor    |   Milestone:  4.8.0
Component:  unknown  |     Version:  4.7.x
 Keywords:           |  
---------------------+------------------------------------------------------
 -O5 causes the addition of C options in csc.scm, while -optimize-level 5
 doesn't.
 Please remove the when-statement that does this.

 Some arguments for this:
 1. -O5 does more than -optimize-level 5, which is undocumented
 and inconsistent.

 2. Furthermore, -fomit-frame-pointer might not help much if the underlying
 chicken was built without this option (if I remember correctly).

 3. -O3 is often not the best choice for speed, so I would recommend not to
 intervene with the settings from the chicken build.

 4. Finally, gcc takes the _last_ -O option if several are given, so -O3
 has no
 effect if "compile-options" contains any -O2 or similar.
