   Bug#31030 rpl000015.test fails if $MYSQL_TCP_PORT != 3306
Note:
  This bug does not occur in MySQL 5.0 and up, because
  ChangeSet 1.2328.2.1 2006/11/27 for MySQL 5.0 prevents this.
  The 5.0 fix uses the environment variable DEFAULT_MASTER_PORT
  which is set by mysql-test-run.pl.
  mysql-test-run.pl in 4.1 does not set this variable.
  There are two alternatives:
  1) Backport the 5.0 fix for this test including modifications
     to mysql-test-run.pl and mysql-test-run-shell.
     This is a not acceptable impact on an old MySQL version.
  2) Fix the problem different than in 5.0 like in the current
     ChangeSet + do not apply these changes when upmerging to 5.0

Denormalized DOUBLE-s can't be properly handled by old MIPS processors.
So we need to enable specific mode for them so IRIX will do use
software round to handle such numbers. 


sql/mysqld.cc:
  Bug #29085 A small double precision number becomes zero.
  
  reset_floating_point_exeption() renamed as set_proper_floating_point_mode()
  #ifdef __sgi code added to enable denormalized DOUBLE-s on IRIX

strmake() calls are easy to get wrong. Add checks in extra
debug mode to identify possible exploits.

  fix off-by-one buffer-length argument to prevent stack smashing
  (already approved, backports #31588)
sql/sql_show.cc:
  misdimensioned buffers: functions further down the callstack
  expect bufsize of FN_REFLEN
sql/unireg.cc:
  When EXTRA_DEBUG is enabled, strmake() will write funny patterns to
  buffers it operates on to identify possibly overflows. This leads to
  badness in mysql_create_frm(), so we explicitly put any unused bytes
  (back) into a defined state. Not a bug-fix, but part of the strmake()
  bug detector.
strings/strmake.c:
  strmake() takes maximum string length rather than buffer-length
  (string length + 1 to accomodate \0 terminator) as argument.
  Since this is easy to get wrong, add extra debug code to identify
  off-by-ones so we can prevent stack smashing.
  
  Alternative "BAD_STRING_COMPILER" removed after checking
  with Monty.

SPATIAL key is fine actually, but the chk_key() function
mistakenly returns error. It tries to compare checksums
of btree and SPATIAL keys while the checksum for the SPATIAL isn't
calculated (always 0). Same thing with FULLTEXT keys is handled
using full_text_keys counter, so fixed by counting both
SPATIAL and FULLTEXT keys in that counter.
