wyjasnienie z INSTALL:

If you encounter a compiler error message complaining about the
lines
      __png.h__ already includes setjmp.h;
      __dont__ include it again.;
This means you have compiled another module that includes setjmp.h,
which is hazardous because the two modules might not include exactly
the same setjmp.h.  If you are sure that you know what you are doing
and that they are exactly the same, then you can comment out or
delete the two lines.  Better yet, use the cexcept interface
instead, as demonstrated in contrib/visupng of the libpng distribution.


chyba mozemy usunac kawalek z pngconf.h bo przy korzystaniu
z prekompilowanych naglowkow daleko nie zajedziemy.
