-Subject: [PATCH] pdf font subset: Generate valid font names
-
-A hash value is encoded in base 26 with upper case letters for font
-names.
-
-Commit ed984146 replaced "numerator = abs (hash);" with "numerator =
-hash;" in this code, because hash has type uint32_t and the compiler
-warned about taking the absolute value of an unsigned value.  However,
-abs() is actually defined to take an int argument. Thus, there was some
-implicit cast.
-
-Since numerator has type long, i.e. is signed, it is now actually
-possible to get an overflow in the implicit cast and then have a
-negative number. The following code is not prepared for this and
-produces non-letters when encoding the hash.
-
-This commit fixes that problem by not using ldiv() and instead using /
-and % to directly compute the needed values. This gets rid of the need
-to convert to type long. Since now everything works with uint32_t, there
-is no more chance for negative numbers messing things up.
