* symfile.c (decrement_reading_symtab): New function.

	* symfile.c, symtab.h (currently_reading_symtab):  New variable.
	* symfile.c (psymtab_to_symtab):  Adjust currently_reading_symtab.
	* gdbtypes.c (check_typedef):  Don't call lookup_symbol if
	currently_reading_symtab (since that could infinitely recurse).
This fixes PR chill/8793.
