OK. After adding this code you suggest:

#ifdef PDF_HOST_WIN32
#   include <windows.h>
#endif

I get:

[...]

libtool: link: rm -fr .libs/libgnupdf.lax

This happens compiling under windows as well as cross compiling.

Hi Pablo.

  And the piece of code from pdf-time.h:

  #ifdef PDF_HOST_WIN32
    /* Windows-specific function to set the time with a pdf_i64_t */
    pdf_status_t
    pdf_time_w32_set_from_filetime (pdf_time_t time_var,
                                    const FILETIME *p_filetime);
  #endif

  This file is missing a windows include for the FILETIME type, if I
  add the include inside this #ifdef, everything goes fine, but
  placing it on the top with other includes (and under the same
  preprocessor condition) messes up the autogenerated pdf.h that's
  used later for compiling tortutils. I don't really know which is
  the best place for this include, as the first fix seems untidy.

The proper way to proceed in this case is to add a PUBLIC block at the
beginning of the file with the inclusion of that header file, like in:

#ifndef PDF_TIME_H
#define PDF_TIME_H

#include <stdio.h>
#ifdef PDF_HOST_WIN32
#   include <FILETYPE.h>
#endif

If that header file causes problem in tortutils when compiling for
mingw32, can you send the output of the compiler?
