+Subject: [PATCH 1/2] tottfgpos.c: fix incorrect sizing of the scripts array
+
+latn contains 58 entries (29 pairs), meaning the size was too small
+to fit the 0 marker at the end of the array

+Subject: [PATCH 2/2] python.c: fix type specifier on long input/return values
+
+int is guaranteed to be at least 16 bits, while long is at least
+32 bits. So for uint32/int32 values, parse longs with the "l"/"k"
+specifier and cast return values to long.
+
+The cast is necessary as on amd64 a long is 64 bits
