Yup; from the autoconf manual:

  If you need to make multiple checks using `test', combine them with
the shell operators `&&' and `||' instead of using the `test' operators
`-a' and `-o'.  On System V, the precedence of `-a' and `-o' is wrong
relative to the unary operators; consequently, POSIX does not specify
them, so using them is nonportable.  If you combine `&&' and `||' in
the same statement, keep in mind that they have equal precedence.
