| dnl (third field in two places below) and set the PNGLIB_RELEASE |
| dnl variable. |
| dnl |
| dnl Major upgrades (incompatible ABI): increment the package major |
| dnl version (second field, or first if desired), set the minor |
| dnl to 0, set PNGLIB_MAJOR below *and* follow the instructions in |
| dnl Makefile.am to upgrade the package name. |

| dnl This is here to prevent earlier autoconf from being used, it |
