* makefile.vms: Add gcc flags to allow compiling with current gcc
snapshot
(targmatch.h): New dependency.
* reloc.c (BFD_RELOC_ALPHA_CODEADDR): New relocation for
openVMS/Alpha.
* evax.h (ALPHA_R_CODEADDR): New relocation.
* evax-alpha.c (ALPHA_R_CODEADDR): 64 bit procedure relocation for
openVMS/Alpha.
* evax-etir.c (ALPHA_R_CODEADDR): Output object code for this
relocation.
* bfd-in2.h, libbfd.h: Rebuild.
Restrict symbol length to 64 bytes, case preserving:
* evax-emh.c (_bfd_evax_write_emh): Remove case hacking.
* evax-misc.c (_bfd_evax_case_hack_symbol): Remove.
(_bfd_evax_length_hash_symbol): Added.
* evax-etir.c (_bfd_evax_write_etir): Call
_bfd_evax_length_hash_symbol before output of symbol.
* evax-egsd.c (_bfd_evax_write_egsd): Likewise.
* evax.h (flag_hash_long_names, flag_show_after_trunc): Remove.
* evax-emh.c: Output filename to object file without path.
* evax-egsd.c: New sections for local and global commons.
* evax-alpha.c, evax-emh.c, evax-egsd.c, evax-etir.c,
evax-misc.c, evax.h: Remove 8 bit characters from copyright
notices. Replace AXP with Alpha.
