In c-aux-info, in gen_aux_info_record, there is a comment that states 
that protoize only works for files in the current working directory, and 
hence it always emits "." for the directory.

Protoize fails when it tries to convert a relative pathname for an 
include file to a full pathname.  It ends up using the directory holding 
the source file instead of using the current working directory, and that 
gives a full pathname that is nonsense.

See invocation_filename in protoize.c.  c-aux-info emits ".", and 
process_aux_info_file converts this into the source file name.  Later 
on, in referenced_file_is_newer, we call abspath with 
invocation_filename, and hence header file names which are relative to 
the objdir get treated as relative to the srcdir.  It isn't clear to me 
if this has ever worked the way you want it to.
