Summary: bdist_wininst preinstall script support is broken in 2.5a1

Initial Comment:
The attached zip file contains a trivial module. Run
"run_setup.bat" to create a bdist_wininst installer
(you'll need to edit it to make the preinstall script
path match where you unzipped the file).

The resulting installer fails with an error "Running the
pre-installation script failed".

bdist_wininst7.1.exe uses runtime dynamic linking to the
python dll.  Python25.dll doesn't export a
PyRun_SimpleString function anymore, it has been replaced by
a macro:
#define PyRun_SimpleString(s) PyRun_SimpleStringFlags(s, NULL)

bdist_wininst *could* be changed to use
PyRun_SimpleStringFlags instead, however, installers built
with previous versions of Python will then refuse to install
pure distributions to Python 2.5.

I have not checked if installers that do *not* have a
pre-install script will work or not.

I suggest to make PyRun_SimpleString an exported function
again - this should be cheap.
