/* Notes on InstallHinfSectionA/W:
 * - InstallHinfSectionW on Win98 and InstallHinfSectionA on WinXP seem to be stubs - they do not do anything
 *   and simply return without displaying any error message or setting last error. We test whether
 *   InstallHinfSectionA sets last error, and if it doesn't we set it to NULL and use the W version if available.
 * - These functions do not return a value and do not always set last error to ERROR_SUCCESS when installation still
 *   occurs (e.g., unquoted inf file with spaces, registry keys are written but last error is 6). Also, on Win98 last error
 *   is set to ERROR_SUCCESS even if install fails (e.g., quoted inf file with spaces, no registry keys set, MessageBox with
 *   "Installation Error" displayed). Thus, we must use functional tests (e.g., is registry key created) to determine whether
 *   or not installation occurred.
 * - On installation problems, a MessageBox() is displayed and a Beep() is issued. The MessageBox() is disabled with a
 *   CBT hook.
