 Thank you very much for giving thoughs to this issue.  I have two additional
 points to add:
 
 1) It would be most useful if gdb could check that the remote and local
 solibs are equal, eg. that their versions, checksums or other identifiers
 or the memory mapping locations such as reported by ldd are the same.
 Otherwise, the host cannot know what really is going on in the target.
 
 2) The texinfo documentation should be updated to include these vaariables.
 In the first place, I was reading info pages and therefore concluded
 that the problem had not been addressed before.  Only after your reply
 I checked "help show" within gdb.
 
 Yours,
 
 Jorma Laaksonen
