Comment(by niels_dekker):

 Hmmm... My commits ([51355] and [51356]) have caused a compile time
 regression failure of Intel Version 9.0 Build 20060222Z (see below).

 I still have to figure out how to work around this issue.  Hopefully the
 commits don't need to be reverted.  Any help is appreciated!
