+dnl Build and run a program to determine if GD has support for the given
+dnl format. The first argument is the proper-noun-capitalized name of the
+dnl format -- basically the word Foo in gdImageCreateFromFoo -- such as
+dnl Png. If support for format Foo exists, the second argument (the name
+dnl of a constant) will be defined to 1. The reason for this charade is
+dnl that gd defines "junk" versions of each gdImageCreateFromFoo function
+dnl even when it does not support the Foo format. Those junk functions
+dnl display a warning but eventually return normally, making a simple link
+dnl or run test insufficient.
