Correct, my bad. Because of seeing MinGW supporting POSIX stuff not
supported by MSVC, I got this wrong impression somehow.

Anyway, in this case it seems that it's okay to use fsetpos() / fgetpos() /
fread() on both files opened by fopen() and _wfopen(), and fread() should do
just what you want - read unformatted bytes into buffer. Are you sure it is
fread() that slows you down?
