 This isn't really a patch, but I couldn't find any other contact
 address for "the gdb developers".
 
 Section 7.8 of the stabs documentation (at
 http://sources.redhat.com/gdb/current/onlinedocs/stabs.html) says:
 
     The `@' type descriptor is for a member (class and variable)
     type. It is followed by type information for the offset basetype,
     a comma, and type information for the type of the field being
     pointed to. (FIXME: this is acknowledged to be gibberish. Can
     anyone say what really goes here?).
 
 I suggest using something along the following lines:
 
     The `@' type descriptor is used together with the `*' type
     descriptor for a pointer-to-non-static-member-data type. It
     is followed by type information for the class (or union), a
     comma, and type information for the member data.
 
     The following C++ source:
 
         typedef int A::*int_in_a;
 
     generates the following stab:
 
         .stabs "int_in_a:t20=*21=@19,1",128,0,0,0
 
 Ben.
