That reminds me.

Tangential to Scott's request, one of the requests from the tool 
developer community that I work with is to add a new wiki article which 
lists all the vendor extensions for the various compilers. Obviously 
this would include but not be limited to the Vendor specific DWARF 
expression operations.
