Does anyone have any input on why 16 bytes from gnu-win32 and
14 for other compiler

WORD is 16 bits=2 bytes, DWORD is 32 bits=4 bytes, so this is

3 * 2 + 2 * 4 = 14

>(gdb) ptype BITMAPFILEHEADER

3 * x + 2 * y = 16

3 * 4 + 2 * 2 = 16

3 * 2 + 2 * 5 = 16

but I can't imagine those types (WORD and DWORD) are anything but 2 and 4 bytes.

Strange.
