Hi Andreas,

I second Bob's suggestion. For completeness of the mailing list, I'd point out again that this is a known problem:

I am using the filedescriptor returned by TIFFFileno() to make additional checks on a given TIFF. Under Linux the code works as expected.

But if I crosscompile the Libtiff and my program with MinGw using:

Libtiff:
  ./configure --host=i686-w64-mingw32

(also CFLAGS=-DO_BINARY does not help)

the lseek() or the read() comes with errno "Bad file descriptor".

Could you point me how to fix that?
