C is full so full of implicit type conversions that it's just not worth
trying to document them all with casts!  Let's look at just one case:

  inline long is_attribute_value_start(char* buffer, long offset) {
    unsigned long character = read_unicode_character(buffer, offset);
    if (character == (long) 0x22 || character == (long) 0x27) {
      return character;
    } else {
      return 0;
    }
  }

Here you cast 0x22 to a long, but it's converted immediately to an
unsigned long.  The return value from read_unicode_character is also
being converted as are the two expressions in the return statements.  I
count five conversions but only two casts.

The real question is why are the types different in the first place?  To
avoid the implicit conversions you could have written this:

  inline unsigned long is_attribute_value_start(char* buffer, long offset) {
    unsigned long character = read_unicode_character(buffer, offset);
    if (character == 0x22ul || character == 0x27ul) {
      return character;
    } else {
      return 0ul;
    }
  }

and I'd change read_unicode_character to return an unsigned long.

But I would not bother, in general, trying to remove them all.  Just
accept that you will (eventually) have to learn C's baroque implicit
type conversions (they have a certain logic to them, just like the
Baroque).  Use the fact that you have casts to find those places where
you have artificial type mismatches (like the above), but otherwise
remove most of them.  As for "natural" type mismatches, I'd leave 0x22
and 0 alone.  The obvious conversion is safe.

Compiler options can also be used to tell you more about these
conversions than you probably want, but it's a good idea to use the from
time to time, just to review any conversions might be problematic.

I just took a look and the most significant non-portable element I say
was the use of a union to get the "packed" Unicode value from some
collection of bytes (i.e. in read_unicode_character).  It all looks
rather odd since it looks like the array is treated as an array of 4-byte
codes rather than a char array.  Anyway, depending on what you do with
it, the union is likely to behave differently on different platforms.
