well seems that GDB/MI is really powerful. I don't know how much stable is the 
interface, but many IDEs already uses it(like eclipse), so maybe it's not to 
hard maintain code based on it ;) anyway, what I would like to change in our 
GDB support is the code like
    
   if (strstr(buf, i18n("No such file or directory.").local8Bit()) 
           ...
   else
           ...

I'm afraid that the output messages produced by GDB can change in future, so 
we will have problems while updating(BUT maybe this isn't true, since the 
GDB/MI iface has changed while the output messages not). I really don't know 
if it is a good idea to switch to GDB/MI, for this reason I wrote this 
prototype, just for checking ;)
