We will however give a warning when opening such a table that users should use ALTER TABLE ... FORCE to fix
the table. In future release we will fix that REPAIR TABLE will be able to handle this case

  Use local seach path for "mysql_priv.h"
mysqld.dsp:
  Added the ARCHIVE storage engine to max
ha_archive.h:
  VC6, but not VC7, needs a cast of byte[] to char* to make
  the compile select the right conversion function in String

  Added BLACKHOLE and FEDERATED storage engines for max builds
  Some preparations for including yaSSL
ha_federated.cc:
  Use local seach path for "mysql_priv.h"

  Check _LONGLONG_TYPE as well, to define 'word64', to make it
  work on Solaris 10 x86_64.
  Can't assume all x86_64 share the same assembler syntax.
  For now disabled assembler for x86_64 and Solaris.

  Use MY_STAT to declare argument to my_fstat()
des_key_file.cc:
  Use local seach path for "mysql_priv.h"
mysys.dsp, libmysqld.dsp, libmysql.dsp:
  New file needed, "../mysys/default_modify.c"
