- Applied some Windows portability fixes for myisampack.c and sql_handler.cc

  (backports from fixes made in 4.1)


myisam/myisampack.c:
   - replaced "1ULL" with "((ulonglong)1)" to resolve a compile error on
     Windows
sql/sql_handler.cc:
   - removed some unused variables
   - added a (byte*) cast to fix a compile error on Windows (backport of a
     fix made in 4.1)
