+===== Problem found =====
+From the above code, it seems that the windows version of ps2pdf doesn't parse options as written in the [[http://pages.cs.wisc.edu/~ghost/doc/AFPL/6.50/Ps2pdf.htm|manual]]:
+<code>
+...
+The usage for ps2pdf is
+    ps2pdf [options] input.[e]ps output.pdf
+...
+</code>
+If I use the following command:
+  ps2pdf "-sPAPERSIZE=a4" in.ps out.pdf
+Analyzing this command from the 'windows' point of view::
+  - ps2pdf.bat is invoked. It gets three arguments: %1, %2 and %3. Specifically:\\ %1 = "-sPAPERSIZE=a4"\\ %2 = in.ps\\ %3 = out.pdf
+  - The text **-dCompatibilityLevel#1.4** is written to a text file called **_.at** which resides in the same directory as your working directory.
+  - If the third argument, %3, is not empty, append the first argument, %1, to the file **_.at**
+  - Shift all arguments out one further, repeat previous step above until only last two arguments are left.
+  - once finished the following command is called:\\ ps2pdfxx %1 %2\\ with %1: in.ps, %2: out.pdf and all [options] are stored in the file **_.at**
