definition, and struct hashnode moved here. Remove the unused
'predefined' field from struct definition. Replace the 'args'
union with its sole member. All users updated (cpphash.c).
Delete HASHSTEP and MAKE_POS macros, and hashf prototype. Add
multiple include guard.
* cpphash.c (hashf): Make static; use better algorithm; drop
HASHSIZE parameter; return an unsigned int.

used. Calculate HASHSIZE modulus here.

here.
(create_definition): Drop PREDEFINITION parameter.

(cpp_notice_from_errno, cpp_ice): New functions.
(cpp_notice): Is now for reporting error conditions, just
without an associated file.
(cpp_error, cpp_error_with_line): Don't do anything if
opts->inhibit_errors is on.
(cpp_pedwarn_with_file_and_line): Take column argument also.
* cpplib.h: Update prototypes of exported functions.
(struct cpp_options): Add inhibit_errors.
* cppalloc.c, cppfiles.c: Use fprintf not cpp_notice for
non-error messages. Include intl.h.
