a comment why no such fix is needed.

in *.h files, so that the function signatures in the *.h and *.c files fully

ut_dulint_sort(): Add a UNIV_INTERN qualifier also to the function definition.

lock_rec_restore_from_page_infimum(): Correct the comment of the parameter rec.

lock_sec_rec_read_check_and_lock(): Add the debug assertion
ut_ad(mode == LOCK_X || mode == LOCK_S).

buf_LRU_old_adjust_len(): Replace a constant ut_ad() with a preprocessor check.

buf_LRU_free_block(): Remove the check for the unlikely case
buf_pool->LRU_old == prev_b in order to simplify the function.
The check was implemented as part of r2306.

suggested by Heikki, because it breaks row_vers_impl_x_locked_off_kernel();
see Mantis issue #10.

However, now that Heikki's fix has been removed, the code may break elsewhere
when it tries to dereference half-freed or completely freed externally
stored columns.

lock_update_delete(): Add the debug assertion ut_ad(page == page_align(rec)).

lock_rec_insert_check_and_lock(): Determine next_rec_heap_no before
acquiring the kernel mutex.  Require the table to be at least S-locked
in fast index creation.

corresponding to a compressed page, do not flag the block as recently
used, but maintain the position of the control block on the LRU list.

lock_rec_get_first(): Use a simple for loop.

lock_rec_copy(): Use mem_heap_dup().

lock_rec_find_similar_on_page(): Add const qualifier to trx.

lock_move_rec_list_end(), lock_move_rec_list_start(): Simplify the
memcmp() assertion on ROW_FORMAT=REDUNDANT records.

Use ut_d() in assignments to bpage->in_LRU_list instead of #ifdef UNIV_DEBUG.

buf_LRU_remove_block(): Move an assertion to a more appropriate place.

Make it easier to display the violating lock request in a debugger.

innobase_check_index_keys(): Remove unused parameters.  Use
sql_print_error() for error message output.

ha_innobase::add_index(): When row_merge_rename_tables() fails, do not
allow row_merge_drop_table() to alter the error code returned to MySQL.

the dynamic InnoDB plugin, ha_innodb.so.  This libtool option cannot
be used on every target platform.  For instance, the AMD64 (x86_64) ABI
mandates position-independent code (PIC) in dynamic shared objects.

Makefile.am: Use $(INNODB_CFLAGS) and $(INNODB_DYNAMIC_CFLAGS) in
target-specific CFLAGS and CXXFLAGS variable definitions.

plug.in: Instead of appending to the MySQL-wide CFLAGS, introduce
the variables INNODB_CFLAGS and INNODB_DYNAMIC_CFLAGS.  Depending on
$target_cpu, append -prefer-non-pic to INNODB_DYNAMIC_CFLAGS.

position-independent code in the compilation of ha_innodb.so.

ha_innodb_la_CXXFLAGS, ha_innodb_la_CFLAGS: Add -prefer-non-pic.
This flag is interpreted by the ../../libtool script that acts
as a front-end to the compiler and linker.

Do not include univ.i in mysql_addons.h, it was included for the sole
purpose of innodb_redefine.h to work and now innodb_redefine.h has been
removed. See r2251 and r2288.

At present, the script only accepts one command line parameter.
Append newline to some die messages, so that the Perl interpreter

include/innodb_redefine.h: Remove.

include/sync0sync.h: Remove the definition of mutex_free that was added
because of innodb_redefine.h.

include/univ.i: Remove references to innodb_redefine.h.  Explain why
the C++ classes need to be renamed.

scripts/build-plugin.sh: Build InnoDB only once.  The file
innodb_redefine.h is no longer needed.

in r2276.  Now the following symbols will be exported when InnoDB is built
as a dynamic plugin:

* the virtual method pointer table of class ha_innodb
* the three variables that MySQL will reference when linking at runtime:

	_mysql_plugin_declarations_
	_mysql_plugin_interface_version_
	_mysql_sizeof_struct_st_plugin_

Furthermore, the following symbols are weak globals, to allow us to access
the built-in InnoDB in the mysqld executable, in case it contains a statically
linked InnoDB:

	builtin_innobase_plugin
	innodb_hton_ptr

pars/pars0grm.h: Remove.  The primary file is include/pars0grm.h.

pars/make_bison.sh: Add from trunk.  Somehow, this file was not merged
at the same time with make_flex.sh.  Add sed magic for replacing the
file name and for hiding yychars, yynerrs, yylval, and yyparse.

pars/pars0grm.c: Apply the changes made by make_bison.sh.

symbols.  Use it for all definitions of non-static variables and functions.

lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static.  It is
referenced from pars0grm.c.

Actually, according to
	nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:

* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs

The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.

The class ha_innodb is renamed from class ha_innobase by a #define.  Thus,
there will be no clash with the builtin InnoDB.  However, there will be some
overhead for invoking virtual methods of class ha_innodb.  Ideas for making
the vtable hidden are welcome.  -fvisibility=hidden is not available in GCC 3.

btr_cur_pessimistic_update(): Note why the externally stored columns
of a record on a latched page cannot have been purged.

trx_undo_get_undo_rec(): Clarify that the stack of versions is locked
all the way down to the purge view.

trx_undo_prev_version_build(): Set *old_vers = NULL also when the record
could have been purged already.  Add some clarifying comments.
