Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become bfd_bread and bfd_bwrite. o bfd_*alloc now all take a bfd_size_type arg, and will error if size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files or bugs in linker scripts etc. o file_ptr becomes a bfd_signed_vma. Besides matching sizes with various other types involved in handling sections, this should make it easier for bfd to support a 64 bit off_t on 32 bit hosts that provide it. o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*) generally available. They now cast their args to bfd_vma and bfd_byte * as appropriate, which removes a swag of casts from the source. o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and aout-encap.c. o Zillions of formatting and -Wconversion fixes.
