	Initial support for PE executables (eg NT, win32)

	* Makefile.in (configure.in, ei386pe): Add support.
	* ldmain.c (main): Initialize PE argument info.
	* ldwrite.c (print_file_stuff): Don't print out .drectve
	and .debug section info.
	* lexsup.c (set_subsystem, set_stack_heap, OPTION_HEAP,
	 OPTION_SUBSYSTEM, parse_argsm set_subsystem, set_stack_heap):
	 Handle new arguments.
	* config/i386-pe.mt, emultempl/i386pe.em, scripttempl/i386pe.sc:
	New files

/* WINDOWS_NT. When an entry point has been specified, we will also force
this symbol to be defined by calling ldlang_add_undef (equivalent to
having switch -u entry_name on the command line). The reason we do
this is so that the user doesn't have to because they would have to use
the -u switch if they were specifying an entry point other than
_mainCRTStartup. Specifically, if creating a windows application, entry
point _WinMainCRTStartup must be specified.
What I have found for non console applications (entry not _mainCRTStartup)
is that the .obj that contains mainCRTStartup is brought in since it is
the first encountered in libc.lib and it has other symbols in it which will
be pulled in by the link process. To avoid this, adding -u with the entry
point name specified forces the correct .obj to be used. We can avoid
making the user do this by always adding the entry point name as an
undefined symbol. */
