guess you need to modify port/cpl_config.h.vc to be aware of HAVE_LONG_LONG
in order to create a compatible port/cpl_config.h (compatible if GDAL has
been compiled with Visual Studio and another package is compiled with
MinGW).

Thanks for fixing this in gdal-trunk!

However, there is still a small issue with the test for GIntBig in
port/cpl_port.h:L226

#if HAVE_LONG_LONG

In cpl_config.h, HAVE_LONG_LONG is either defined and set to 1, or it is
not defined. Therefore L226 should be

#if defined(HAVE_LONG_LONG)

or to be really sure that you have long long

#if defined(HAVE_LONG_LONG) && HAVE_LONG_LONG

but IMHO it is wrong to assume that HAVE_LONG_LONG is always defined and
either zero or non-zero.
