Ah, it's this again: http://trac.osgeo.org/gdal/ticket/2649

I'm using MinGW, which uses MS runtime and thus _MSC_VER is, IMO, *not* 
the correct macro to check, as the wide functions are available in the 
runtime, which can be used by other compilers also. Changing the 
_MSC_VER test to defined(MSVCRT) in cpl_vsil_win32.cpp and adding 
-D__MSVCRT_VERSION__=0x0601 to GDALMake.opt(1) fixes the problem for MinGW.

I'm not sure which would be the correct fix. Does MSVC define 

That also seems to make the GTK+ and Perl interface work ok, i.e., a 
GTK+ stock file open dialog starts to work for data with skandinavian 
characters in the filename. :)
