[PATCH] Dwarf2 "main" pointer die for VMS

[Douglas B Rupp]

I made your recommend changes and was doing some final testing when I 
realized the patch depends on some new prologue/epilogue debug labels 
introduced in this as yet unreviewed patch:

http://gcc.gnu.org/ml/gcc-patches/2009-07/msg01339.html

I see you're a designated debug reviewer, so perhaps you could take a 
look at it if convenient.
