FLOATING_POINT options were switched off, png.h ended up with lone ';' characters. This is not valid ANSI-C outside a function. The ';' characters have been moved inside the definition of PNG_FP_EXPORT and PNG_FIXED_EXPORT. 2) If either option was switched off, the declaration of the corresponding functions were completely omitted, even though some of them are still used internally. The result is still valid, but produces warnings from gcc with some warning options (including -Wall). The fix is to cause png.h to declare the functions with PNG_INTERNAL_FUNCTION when png.h is included from pngpriv.h.

Fixed a memory overwrite bug in simplified read of RGB PNG with non-linear gamma Also bugs in the error checking in pngread.c and changed quite a lot of the checks in pngstest.c to be correct; either correctly written or not over-optimistic. The pngstest changes are insufficient to allow all possible RGB transforms to be passed; pngstest cmppixel needs to be rewritten to make it clearer which errors it allows and then changed to permit known inaccuracies.

The API is extremely inaccurate for sRGB conversions because it uses an 8-bit intermediate linear value and it does not use the sRGB transform, so it suffers from the known instability in gamma transforms for values close to 0 (see Poynton). The net result is that the calculation has a maximum error of 14.99/255; 0.5/255^(1/2.2). pngstest now uses 15 for the permitted 8-bit error. This may still not be enough because of arithmetic error.
