Thanks for confirming that this is not just a problem on my system.

I found the problem. OpenAL has initialization and deinitialization
functions alc_init() and alc_deinit(), defined in Alc/ALc.c. On Windows,
these are called via automatic execution of DllMain by default. In our
case, we have to use the gcc constructor/destructor attributes instead,
like non-Windows platforms do.

The attached patch makes this change by augmenting the
openal-1-fixes.patch file.

Both openal-info.exe and test-openal.exe now work for me.
