Wed Feb  7 14:12:03 1996  Ian Lance Taylor  <ian@cygnus.com>

        * configure.in: Check for --enable-shared.  If linking against
        shared BFD and opcodes, fix library name on SunOS, and try to set
        -rpath reasonably.
        * configure: Rebuild.

Tue Feb  6 15:16:17 1996  Ian Lance Taylor  <ian@cygnus.com>

        * Many files: For MRI syntax that is specific to the m68k MRI
        assembler, check flag_m68k_mri rather than flag_mri or
        MRI_MODE_NEEDS_PSEUDO_DOT.

Mon Feb  5 16:29:11 1996  Ian Lance Taylor  <ian@cygnus.com>

        (targ_has_iclass): Handle ARCH_HX.
        (tc_coff_fix2rtype): Add return 0 to avoid warning.
        (tc_headers_hook): If the architecture was specified explicitly,
        use it when setting the flags.  Set the extern variable coff_flags
        rather than headers->filehdr.f_flags, since the latter is set
        unconditionally in obj-coff.c.
        (i960_handle_align): Remove unused variable fixp.

        Support for building bfd and opcodes as shared libraries, based on
        patches from Alan Modra <alan@spri.levels.unisa.edu.au>:

        undefined or common symbol.
        * config/obj-bout.h (S_IS_COMMON): Define if not BFD_ASSEMBLER.

        undefined or common symbol.
        * config/obj-coff.c (do_relocs_for): Use S_IS_DEFINED and

        frag_append_1_char): Refer to frchain_now->frch_obstack instead of
        frags variable.
        (frag_new): Ditto.  Verify that frch_last and frag_now match on
        entry and exit, and that old frag_now has non-zero type.  Replace

        section, set frchain_now to absolute_frchain.  Verify that
        frch_last and frag_now match on entry and exit.  Initialize
        per-chain obstack, and under gcc, set required alignment to that
        needed by fragS structure.

        memory allocation rules.
