True, but it causes the Digital Unix compiler to issue warnings.
Every compiler except for GCC issues great gobs of warnings when
compiling ltdl.c and it would be nice to see the number of warnings
reduced to zero.

The oodles of warnings issued while compiling ltdl.c causes the
package I maintain to appear of much lower quality than it actually
is.
