Hello!
I've got some problems with "pending breakpoints" functionality, using MI
interface. Here's example session:

   (gdb) break helper.cpp:4 
   break helper.cpp:4
   No source file named helper.cpp.
   Breakpoint 2 (helper.cpp:4) pending.
   ^done
   (gdb) -break-insert helper.cpp:5 
   No source file named helper.cpp.
   ^done

The CLI command correctly adds pending breakpoint. The helper.cpp file is in
dlopen-ed shared library, and the breakpoint will be resolved when the
library is loaded.

The MI command neither errors out (the reply is "^done", not "^error"), nor
it does anything. It does not report breakpoint number, it does not add any
breakpoint at all.

What is the reason for this? Is this a bug? How do other frontend authors
deal with breakpoints in shared libraries, then?

Thanks in advance,
Volodya
