* libc/include/sys/config.h[__mips__]: Don't bother
setting __ATTRIBUTE_IMPURE_PTR__ here.
[__rtems__][__mips__]: No need to undef the __ATTRIBUTE_IMPURE_PTR__
macro anymore.
* libc/include/pthread.h: Remove prototypes for
pthread_attr_getcputime and pthread_attr_setcputime which
were proposed but never approved by the POSIX standard.
* elf.c (assign_file_positions_for_load_sections): Use header_size
to avoid moving the load address of file headers.
(assign_file_positions_for_load_sections): Set header_size for
segments containing the file header.
include/elf/
* internal.h (struct elf_segment_map): Add header_size field.
(GetProcessDEPPolicy): Ditto.
(SetProcessDEPPolicy): Ditto.
* dcrt0.cc (disable_dep): New static function.
(dll_crt0_0): Call disable_dep on platforms requiring it. Add longish
comment to explain the circumstances.
* wincap.h (wincaps::ts_has_dep_problem): New element.
* wincap.cc: Implement above element throughout.
(wincapc::init): Set ts_has_dep_problem to true on 2008 Terminal
Servers.

DOS drive letter to accommodate case sensitivity.
(cygdrive_getmntent): Ditto.

(start_at): Ditto.
(ucreqenv): New function to uppercase only the environment variables
from renv_arr.
(parse_thing): Add "upcaseenv" setting.
(environ_init): Parse $CYGWIN before doing anything else. Call
ucreqenv instead of ucenv if CYGWIN=noupcaseenv is set.
recursion_counter is already 0.
(pthread_mutex::_destroy): Don't consider a mutex busy if its recursion_counter
== 0.
(pthread_mutex::_fixup_after_fork): Set recursion_counter to 0 to flag that
we've just forked. Don't reset the owner of this mutex since the forkee may
think it still owns the mutex. Reinstate initialization of win32_obj_id.
* fhandler_floppy.cc (fhandler_dev_floppy::raw_read): Initialize a variable to
bypass a C++ warning.
for the newly opened handle. Explain why.
