code to update nread as each character is processed instead
of using buffer contents which throw away leading zeroes.

to set_process_privileges().

by a call to get_file_attribute(). Discard local variable has_acls.
Slightly reformatted.

to rootdir(). Don't call num_entries() on remote drives.

simplify code.
* sigproc.cc (sig_send): Remove debugging statement.
* elf32-mips.c (mips_elf_next_relocation): Rename from
mips_elf_next_lo16_relocation, and generalize to look
for any relocation type.

implementation doesn't have special handling for switch
statements.
(macro_build): Allow for code in sections other than .text.
(macro): Likewise.
(mips_ip): Likewise.
(md_apply_fix): Do pc-relative relocation madness for MIPS ELF.
Don't perform relocs if we will be outputting them.
(tc_gen_reloc): For ELF, just use fx_addnumber for pc-relative
relocations. Allow BFD_RELOC_16_PCREL_S2 relocs when
embedded-pic.
