+Allow usage when fork() is not available
+
+When fork() is not available, we need to define NO_ZPIPE so that
+libXpm doesn't try to fork/exec to use a pipe to uncompress compressed
+.xpm files. There is obviously a loss of functionality, but loading
+uncompressed .xpm files should continue to work.
