ENH: Use <> instead of quotation marks for header includes

The following header files are present multiple times in the directories
list.
	rtnhdr.h        sr_unix sr_unix_nsb
	zbreaksp.h      sr_unix sr_i386
	emit_code.h     sr_port sr_i386
	auto_zlink.h    sr_unix sr_i386
	obj_filesp.h    sr_unix sr_unix_nsb
	opcode_def.h    sr_port sr_unix_nsb

This over lap meant that a #include "header.h" chose the header in the
same directory as a C file instead of the one listed in the compile line
include directory listing.
