Unfortunately, getting rid of the [] around the echo statements
doesn't solve it.  Autoconf still complains as before, and then the
configure script fails with:

checking for SDL_IMAGE... ../configure: line 8532: syntax error near
unexpected token `('

Although the current code seems to work (after a second autoreconf),
these error messages worry me.  What's more, even by deleting the echo
statements entirely, I can't seem to get back to a state that doesn't
generate these errors.  Anyway, thanks.
