Comment (by wolfgang.lux@…):

 I have been bitten by the just the same bug today. In order to fix
 WindowMaker, the following patch must be applied to  wrlib/png.c:
 --- wrlib/png.c.orig    2004-10-12 20:22:04.000000000 +0200
 +++ wrlib/png.c 2012-10-08 19:41:57.000000000 +0200

      }

      RErrorCode = RERR_INTERNAL;
 -    if (setjmp(png->jmpbuf)) {
 +#ifndef png_jmpbuf
 +# define png_jmpbuf(png) (png)->jmpbuf
 +#endif
 +    if (setjmp(png_jmpbuf(png))) {
          fclose(f);
          png_destroy_read_struct(&png, &pinfo, &einfo);
          if (image)
