Follow on questions:

1. I had done my initial development from the elfutils-0.154 tarball, 
not from a git tree.  From the tarball all I had to do was "configure" 
and "make".  The git tree is missing a configure file and various 
Makefile.in's (and a few other things).  I can copy the missing files 
into the tree and continue, but I'm sure that's not the best way.  
What's the best way?

2. When building, the compiler complains about readelf.c -- it's missing 
one line in the table "known[]" inside print_ops(), for the value of 
DW_OP_GNU_parameter_ref, which is referenced in a case statement and a 
printf() right before the "default" at about line 4420.  It's trivial to 
add this as the last line in the known[] table.

3. elflint.c, at line 954, generates an error:

     section [36] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x20c28 
does not match .got.plt section address 0x20cb8

for many of the *.so files it checks.  This is because the *.so 
intentionally points to ".got" rather than ".got.plt".  Our gcc guy 
doesn't believe this is an error.

Thanks.
