[pdf-devel] Public header generation

[Aleksander Morgado]

Hi all,

I modified the pdf.h generation in src/Makefile.am so that some extra 
things are added:
1. File details and GPL version header
2. Check for the definition of PDF_H, and define it if not already done, 
to avoid multiple inclusions of the header.

Here is the patch.
