[Nick Clifton]

Hi Guys,

  I have checked in a patch to add missing prototypes for the
  following files:

    coff-a29k.c, coff-apollo.c, coff-arm.c, coff-i860.c,
    coff-rs6000.c, coff-tic80.c, elf-m10200.c,
    elf-m10300.c, elf32-arm.h, elf32-d10v.c, elf32-m32r.c,
    elf32-mcore.c, elf32-openrisc.c, elf32-sh.c,
    elf32-sparc.c, elf32-v850.c, elfarm-nabi.c, elfarm-oabi.c

Cheers
