This is not related to vxWorks at all; we will continue to support vxWorks 
5.5.x for as long as possible, but this question relates only to systems using 
the Posix OSD routines in libCom.  Our vxWorks OSD routines do not use those 
Posix routines.

I suspect not, have you tried it on Linux?  Assuming that does what you need 
I'd say go ahead and we can test the result to ensure it doesn't break other 
architectures later.
