+Here's what's to be done for maintaining GNU Binutils.

+# Configuration

+a.out support and 64 bit support are not interesting.
+
+  * `bfd/`
+
+      * `config.bfd`
+
+          * `i[3-7]86-*-gnu*`
+
+            Comparing to `i[3-7]86-*-linux-*`:
+
+              * `i386linux_vec` -- a.out.
+
+              * `i386pei_vec`
+
+                *BFD back-end for Intel 386 PE IMAGE COFF files*.  Not interesting.
+
+              * 64 bit.
+
+      * `configure.host`
+
+        Souldn't need anything.  x86 Linux neither.
+
+      * `configure.in`
+
+        Linux:
+
+          * `COREFILE=trad-core.lo` with `TRAD_HEADER='"hosts/i386linux.h"'`
+
+            We don't have any such core file support configured.  Should we?
+            Where is this core file reading exactly used?  GDB?
+
+          * `i386linux_vec` -- a.out.
+
+          * `i386pei_vec`
+
+            *BFD back-end for Intel 386 PE IMAGE COFF files*.  Not interesting.
+
+  * `binutils/`
+
+      * `configure.tgt`
+
+  * `gas/`
+
+      * `config/te-gnu.h`
+
+        C.f. `te-linux.h`; search tree for `TE_LINUX` vs. `TE_GNU` usage.
+
+          * `tc-i386.h`
+
+            Sole `TE_LINUX` usage is for a.out.
+
+      * `configure.tgt`
+
+  * `ld/`
+
+     * `configure.host`
+
+         * `*-*-gnu*`
+
+            Resolve `crt0.o` vs. `crt1.o` issue.
+
+      * `configure.tgt`
+
+          * `i[3-7]86-*-gnu*`
+
+            Compare to `i[3-7]86-*-linux-*`, but don't need a.out (`i386linux`)
+            and 64 bit support.
