innobase/dict/dict0dict.c:
  Applied innodb-4.1-ss36 and innodb-4.1-ss38 snapshots
  
  Revision r36:
  innodb-4.1: Port r1030 from innodb/branches/5.0:
  
  Replace isspace() with a wrapper ib_isspace(), because on
  Win32 isspace(0xa0) appears to hold.  (Bug #24299)
  
  
  Revision r38:
  ib_isspace(c): Check for c being the null character.  (Bug #25596)
