Re: Questions about gdb/mi support on the Mac

[Jim Ingham <jingham@apple.com>]

As Daniel said, we've pretty freely changed the MI interfaces to make  
them work with ProjectBuilder, then "Project Builder" then Xcode.   
When we started working on this 6 years ago, the MI interfaces were  
pretty rudimentary, so this was necessary.  And there wasn't much  
interest in taking MI changes for the first couple of years we were  
working on it here, so we gradually drifted apart.

There have been several rounds of pulling from our sources to the FSF  
version by various kind folks on the net - though these often  
introduced other subtler differences.  I haven't ever catalogued what  
we've changed, however, so I can't off the top of my head tell you  
what is different.  Most of the changes we made to input syntax are  
documented either in our version of the manual, or in the function  
headers to the mi implementation functions.  The output changes are  
less well documented.  And in our sources we've tried to mark our  
local diffs with "APPLE LOCAL"; but with the MI stuff, where there are  
many whole sections of code that we've added, we are less careful  
about this.

There was a short-lived attempt to rationalize the MI interfaces.  It  
seems to have gone quiet, however - I don't think anybody who's  
actually working on gdb had sufficient motivation to make it worth the  
time it would take to actually do this.
