-   - Return strtol_error, and store any result through an additional
-     TYPE *VAL pointer instead of returning the result.
-   - If TYPE is unsigned, reject leading '-'.
-   - Behavior is undefined if BASE is negative, 1, or greater than 36.
-     (In this respect xstrtol acts like the C standard, not like POSIX.)
-   - Accept an additional char const *VALID_SUFFIXES pointer to a
-     possibly-empty string containing allowed numeric suffixes,
-     which multiply the value.  These include SI suffixes like 'k' and 'M';
-     these normally stand for powers of 1024, but if VALID_SUFFIXES also
-     includes '0' they can be followed by "B" to stand for the usual
-     SI powers of 1000 (or by "iB" to stand for powers of 1024 as before).
-     Other supported suffixes include 'K' for 1024 or 1000, 'b' for 512,
-     'c' for 1, and 'w' for 2.
-   - Suppose that after the initial whitespace, the number is missing
-     but there is a valid suffix.  Then the number is treated as 1.  */
