re PR java/13948 (GCJ segmentation fault while compiling GL4Java .class files) 

Fixes PR java/13948
	* parse.y (java_layout_seen_class_methods): Ensure class is loaded
	before trying to lay out its methods.
	* jcf-parse.c (read_class): Track parsed files using canonical paths
	obtained via lrealpath from libiberty.
	(java_parse_file): Likewise.
	(parse_source_file_1): Rename formal parameter to reflect its
	modified purpose. Minor formatting fix.
