	* pex-djgpp.c: Include string.h, fcntl.h, unistd.h, and
	sys/stat.h.
	(pex_init): Fix last argument to pex_init_common.
	(pex_djgpp_exec_child): Remove leading underscore from _open,
	_dup, _dup2, _close, and _spawnv/_spawnvp.  Replace `program',
	which is undeclared, with `executable', which was unused.  Remove
	unused variable `e'.  Fix casting of last arg to spawnv/spawnvp.
	(pex_djgpp_wait): Declare arguments with ATTRIBUTE_UNUSED.
