(getenv_internal) [WINDOWSNT]: Use strnicmp, not bcmp.

(child_setup): Use IS_DIRECTORY_SEP.
[WINDOWSNT]: Call prepare_standard_handles.  Use spawnve.
Use reset_standard_handles.

(Fcall_process_region): Test DOS_NT, not MSDOS.
(Fcall_process) [WINDOWSNT]: Call pipe_with_inherited_out.
Use the return value of child_setup to get the child's pid;
don't call vfork etc. explicitly.

[WINDOWSNT]: Add includes.  Defone NOMINMAX, _P_NOWAIT.
(Vbinary_process_input, Vbinary_process_output)
(Qbuffer_file_type): Test DOS_NT, not MSDOS.
(syms_of_callproc): Test DOS_NT, not MSDOS.

(init_callproc): Test DOS_NT, not MSDOS.
