DWORD is an alias for 'unsigned long' in 32bit Windows.
Do you know how it defined in 64bit Windows?

Postgres requires sizeof(long) = sizeof(void *), but sizeof(DWORD) is
always 4. I fear the formatter for long integer might be broken
in 64bit platform.

If we could expect C99 is always available, 'PRIu32' would be the best choice.
