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.
