I first that at = first too, but then I realized that it doesn't do it. The gdb-mi.el sou= rce has the following logic.

=C2=A0 (gdb-input
=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 ; Needs = GDB 6.2 onwards.
=C2=A0=C2=A0 (list "-file-list-exec-source-files" 'gdb-get-so= urce-file-list))
=C2=A0 (if gdb-create-source-file-list
=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0 (gdb-input
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 ; Needs GDB 6.0 onwards.
=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 (list "-file-list-exec-source-file&q= uot; 'gdb-get-source-file)))

i.e. the gdb command "-file-list-exec-source-files" (note the= s in files) is called independantly from gdb-create-source-file-list which= only influences the execu= tion of "-file-list-exec-source-file".

Customize gdb-create-source-file-list to nil.
