Starting at 5.1.38, MySQL server exports symbols needed
for dynamic plugin on Windows. There is no need for
Windows specific loading. Also, the CMake files are
simplified in 5.1.38.

When WITH_INNOBASE_STORAGE_ENGINE is specified during
configuration (win\configure.js), InnoDB is built as
a static library. Otherwise, a dynamic InnoDB will be
built (ha_innodb.dll).

CMakeLists.txt requires minor changes in order to work
with MySQL prior to 5.1.38. The changes will be in a
separate patch.

This patch addresses Mantis issue#286.
