	* emultempl/pe.em (PE_DEF_SECTION_ALIGNMENT): If
	OVERRIDE_SECTION_ALIGNMENT is defined, change to that.
	(gld_${EMULATION_NAME}_before_parse): Use EXECUTABLE_NAME if it is
	defined, rather than a.exe.
	(init): Define __subsystem__ as ${SUBSYSTEM}.
	(set_pe_subsystem): Add ${INITIAL_SYMBOL_CHAR} before entry symbol
	name.
