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.
