I just tried to cross-build latest git OpenOCD (using libftdi) under Linux. It
seems to me Win32 build with MinGW.org 32bit compiler is okay.
But then I got build error with MinGW-w64.

make[6]: *** [ft2232.lo] Error 1
The problem seems to be that the defintion has already been
included inside libftdi-0.18. And the MinGW-w64 compiler seems
to be more stringent.
ft2232.c:
#define LIBFTDI_READ_RETRY_COUNT 2000
#ifndef BUILD_FT2232_HIGHSPEED
#if BUILD_FT2232_FTD2XX == 1
enum { FT_DEVICE_2232H = 6, FT_DEVICE_4232H };
#elif BUILD_FT2232_LIBFTDI == 1
enum { TYPE_2232H = 4, TYPE_4232H = 5 };
#endif
#endif
ftdi.h from libftdi-0.18
/** FTDI chip type */
enum ftdi_chip_type { TYPE_AM=0, TYPE_BM=1, TYPE_2232C=2, TYPE_R=3,
TYPE_2232H=4, TYPE_4232H=5 };
Commenting out the following two lines seems to solve the issues.
But I am not so sure if this is the proper fix and why these two
lines are there (an older version of libftdi?)
#elif BUILD_FT2232_LIBFTDI == 1
enum { TYPE_2232H = 4, TYPE_4232H = 5 };
