* src/options.h (NULLSTRINGS): New enum value.
(Options::get_stringpool_name, Options::set_stringpool_name): New
method declarations.
(Options::_stringpool_name): New field.
* src/options.icc (Options::get_stringpool_name): New method.
* src/options.cc (DEFAULT_STRINGPOOL_NAME): New variable.
(Options::long_usage): Document -Q and --null-strings.
(Options::Options): Initialize _stringpool_name.
(Options::~Options): Output _stringpool_name, NULLSTRINGS values too.
(Options::set_stringpool_name): New method.
(long_options): Add options --string-pool-name, --null-strings.
(Options::parse_options): Implement options -P, -Q and --null-strings.
* src/input.cc (Input::read_input): Recognize declarations %pic,
%define string-pool-name, %null-strings.
* src/output.h (Output::output_string_pool,
Output::output_lookup_pools): New method declarations.
(Output::_wordlist_eltype): New field.
* src/output.cc (Output::output_keylength_table): Trivial
simplification.
(Output::output_string_pool): New method.
(output_keyword_entry): Add stringpool_index argument. For SHAREDLIB,
use struct offsets.
(output_keyword_blank_entries): For SHAREDLIB, use -1 instead of "".
(Output::output_keyword_table): Use _wordlist_eltype instead of
_struct_tag. Compute stringpool_index for output_keyword_entry.
(Output::output_lookup_pools): New method.
(Output::output_lookup_function_body): Use _wordlist_eltype instead of
_struct_tag. For SHAREDLIB, use "+ stringpool" to convert offsets to
strings. Use "o >= 0" to test for nonempty table entry.
(Output::output_lookup_function): Call output_lookup_pools.
(Output::output): Initialize _wordlist_eltype. Call
output_lookup_pools.
* tests/jstest4.gperf: New file.
* tests/test-6.exp: Update.
* tests/Makefile.in (check-lang-syntax): Drop test of -p. Add tests of
-P and -Q.
* doc/gperf.texi (User-supplied Struct): Mention that first field has
to be of type 'int' if -P is given.
(Gperf Declarations): Document %pic, %define string-pool-name,
%null-strings.
(Output Details): Update description of option -P. Document options -Q
and --null-strings.
* tests/Makefile.in (check-link-c, check-ada, check-pascal,
check-test): Omit option -p.
* tests/c-parse.exp: Regenerated.

the table's size will grow as needed. Earlier versions of gperf bailed
out with an "Internal error, duplicate hash code value".
* The options -f/--fast and -o/--occurrence-sort have no effect any more.
* Added option -P/--pic that optimizes the generated code for use in shared
libraries.
* Added options -P/--pic and --null-strings that optimize the generated code
for use in shared libraries. -P/--pic does a perfect optimization but may
require some small code changes (see the documentation for details), whereas
--null-strings does only a half-hearted optimization but works without
needing any change to surrounding code.
* Added option --ignore-case that produces a case independent lookup function.
* Bug fixes.

Optimize the generated table for inclusion in shared libraries. This

the generated code. If the @samp{%struct-type} declaration (or,
equivalently, the option @samp{-t}) is also given, the first field of the

-P, --pic Optimize the generated table for inclusion in shared
libraries. This reduces the startup time of programs
using a shared library containing the generated code.
-Q, --string-pool-name=NAME
Specify name of string pool generated by option --pic.
Default name is 'stringpool'.
--null-strings Use NULL strings instead of empty strings for empty
keyword table entries.
-W, --word-array-name=NAME
Specify name of word list array. Default name is
'wordlist'.
