+
+Hi,
+
+The reason that building nss (i.e., firefox) would segfault on ARM EABI
+systems is an assumption about the layout of the jmp_buf structure in
+the nspr library (which nss depends on) that does hold on old-ABI but
+no longer holds on EABI.  The attached patch fixes this assumption,
+and fixes the shlibsign segfault during the building of nss (it also
+fixes a floating point byte order assumption.)
+
+Looks sane?
+
+It's of course a stupid idea to depend on a particular layout of the
+jmp_buf structure in application programs, but oh well.  People write
+ugly buggy code, film at 11.
