           Summary: [3.4 Regression] GCC cannot find t/t.h if t is a file
                    and t/t.h is in subdirectory temp
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Keywords: rejects-valid
          Severity: critical
          Priority: P2
         Component: preprocessor
        AssignedTo: neil at gcc dot gnu dot org
        ReportedBy: pinskia at physics dot uc dot edu
                CC: gcc-bugs at gcc dot gnu dot org
GCC target triplet: *-*-*

When a file with the same name as a directory which you want to lookup, the 
preprocessor now rejects this:
touch t
mkdir temp
mkdir temp/t
echo "HELLO">temp/t/t.h
echo "#include \"t/t.h\"">t.c
gcc -I. -Itemp t.c
     t.c:1:17: t/t.h: Not a directory

This cause gdbtk to not be able to build.

The line with the include should be echo '#include "t/t.h"' > t.c

        * Makefile.in (LIBCPP_DEPS): Add HASHTAB_H.
        * cppfiles.c: Completely rewritten.
        * c-incpath.c (free_path, remove_duplicates, heads, tails, add_path):
        struct cpp_path is now struct cpp_dir.
        (remove_duplicates): Don't simplify path names.
        * c-opts.c (c_common_parse_file): cpp_read_next_file renamed
        cpp_stack_file.
        * cpphash.h: Include hashtab.h.
        (_cpp_file): Declare.
        (struct cpp_buffer): struct include_file is now struct _cpp_file,
        and struct cpp_path is now struct cpp_dir.  Rename members.
        (struct cpp_reader): Similarly.  New members once_only_files,
        file_hash, file_hash_entries, quote_ignores_source_dir,
        no_search_path, saw_pragma_once.  Remove all_include_files and
        max_include_len.  Make some members bool.
        (_cpp_mark_only_only): Renamed from _cpp_never_reread.
        (_cpp_stack_file): Renamed from _cpp_read_file.
        (_cpp_stack_include): Renamed from _cpp_execute_include.
        (_cpp_init_files): Renamed from _cpp_init_includes.

        (do_include_common, _cpp_pop_buffer): Update.
        (do_import): Undeprecate #import.
        (do_pragma_once): Undeprecate.  Use _cpp_mark_file_once_only.
        * cpplib.h: Remove file_name_map_list.
        (cpp_options): Remove map_list.
        (cpp_dir): Rename from cpp_path.  New datatype for name_map.
        (cpp_set_include_chains, cpp_stack_file, cpp_included): Update.
