 version 1.2.42beta01 [December 4, 2009]
   Removed "#define PNG_NO_ERROR_NUMBERS" that was inadvertently added
     to pngconf.h in version 1.2.41.
+  Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
+    to put png.h and pngconf.h in $prefix/include, like the other scripts,
+    instead of in $prefix/include/libpng.
