A @dfn{preprocessing token} is a @dfn{preprocessing number} if it
begins with a digit and is followed by letters, underscores, digits,
-periods and @samp{e+}, @samp{e-}, @samp{E+}, or @samp{E-} character
-sequences.
+periods and @samp{e+}, @samp{e-}, @samp{E+}, @samp{E-}, @samp{p+},
+@samp{p-}, @samp{P+}, or @samp{P-} character sequences. (In strict C89
+mode, the sequences @samp{p+}, @samp{p-}, @samp{P+} and @samp{P-} cannot
+appear in preprocessing numbers.)
To make the above program fragment valid, place whitespace in front of
the minus sign. This whitespace will end the preprocessing number.
