*	unpack.c: Cast negative signed offset to signedHEAD master	Tomasz Kramkowski	2022-11-02	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	As N1570§6.5.16.2p3 states, E1 += E2 is equivalent to E1 = E1 + (E2). This means that E1 + (E2) will be subject to (6.5.6p4) "the usual arithmetic conversions". Since both types have equal integer conversion rank (6.3.1.1p1), E1 which was intmax_t will first be converted to uintmax_t before being added to (E2). This is not the intended result as it relies on integer wrapping behaviour again. Casting E2 to intmax_t first prevents the conversion of E1 and produces the correct result.

*	Define PRIuSIZE to avoid issues compiling with msvcrt	Tomasz Kramkowski	2021-08-05	1	-4/+4
\| \| \| \| \| \| \| \|	On windows and when cross compiling with mingw the standard library only supports C89 which means that print format arguments cannot take "%zu". To fix this, a PRIuSIZE macros is needed which expands to PRIu32 on windows 32 bit and PRIu64 on windows 64 bit.

*	unpack: Fix negative signed integer unpacking calculation	Tomasz Kramkowski	2021-05-31	1	-3/+13
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Currently the calculation is just wrong since it effectively relies on the widths of the signed and unsigned integer types and on wrapping-on-assignment behavior. I have no idea why I wrote it like this, it seems obviously wrong in retrospect. The new behavior ensure that this succeeds in situations where type widths are not correct. The new code sets vals to the minimum possible two's complement signed value (I just realised this code now assumes two's complement) and then offsets it with the value part of the signed integer.
