Section 3.1 says:

Padding is performed as follows: "i" bytes of value "i" are appended to the message so that the length in bytes of the padded message becomes congruent to 0, modulo 16. At least one byte and at most 16 16 bytes are appended.

It should say:

Section 3.2 says:

... /* Process each 16-word block. */ For i = 0 to N/16-1 do /* Checksum block i. */ For j = 0 to 15 do Set c to M[i*16+j]. Set C[j] to S[c xor L]. Set L to C[j]. end /* of loop on j */ end /* of loop on i */ The 16-byte checksum C[0 ... 15] is appended to the message. Let M[0 with checksum), where N' = N + 16.

It should say:

... /* Process each 16-word block. */ For i = 0 to N/16-1 do /* Checksum block i. */ For j = 0 to 15 do Set c to M[i*16+j]. Set C[j] to C[j] xor S[c xor L]. Set L to C[j]. end /* of loop on j */ end /* of loop on i */ The 16-byte checksum C[0 ... 15] is appended to the (padded) message. Let M[0..N'-1] be the message with padding and checksum appended, where N' = N + 16.

Section 3.2 says:

Set L to 0. /* Process each 16-word block. */ For i = 0 to N/16-1 do /* Checksum block i. */

It should say:

Set L to 0. /* Process each 16-byte block. */ For i = 0 to N/16-1 do /* Checksum block i. */

Notes:

The comment should note that this section of the algorithm operates on a 16 byte -- rather than 16 word -- block.
