Not in that section, but it does elsewhere in the section on test (and
it is portable):
It is safe to use `!' as a `test' operator. For example, `if test
! -d foo; ...' is portable even though `if ! test -d foo; ...' is
not.
The later chapters of recent versions of the autoconf manual are a handy
reference for portability information about shell and other matters.
