If you encounter a compiler error message complaining about the

__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.

Y2K compliance in libpng:
=========================
August 15, 2004
August 26, 2004
Since the PNG Development group is an ad-hoc body, we can't make
an official declaration.
This is your unofficial assurance that libpng from version 0.71 and
upward through 1.2.6 are Y2K compliant. It is my belief that earlier
upward through 1.2.7beta1 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
Libpng only has three year fields. One is a 2-byte unsigned integer

## dummy dependencies for each header file. Too bad gcc doesn't do
