/**

 * On Windows, DWORD and ULONG are defined to unsigned long.

 * However, 64-bit Windows uses the LLP64 model which defines

 * unsigned long as a 4-byte type, while most non-Windows

 * systems use the LP64 model where unsigned long is 8 bytes.

 *

 * WinPR correctly defines DWORD and ULONG to be 4-byte types

 * regardless of LLP64/LP64, but this has the side effect of

 * breaking compatibility with the broken pcsc-lite types.

 *

 * To make matters worse, pcsc-lite correctly defines

 * the data types on OS X, but not on other platforms.
