When I compile libssh 7.5 with the VS2015 compiler I get the following
two warnings:
fe25519.c(92):
warning C4146: unary minus operator applied to unsigned type, result
still unsigned
fe25519.c(145): warning C4146: unary minus operator applied to unsigned
type, result still unsigned
The two lines of code are:
m = -m;
and
mask = -mask;
where both m and mask are defined as crypto_uint32. What is the
intended result of apply a unary minus operator to the unsigned types?
m = (uint32_t) ( -(int32_t)m);
