I'm working on building Git on Visual Studio as part of the Git for Windows
capability.
The MSVC compiler is reporting:
1>..\sha1-lookup.c(100) : warning C4146: unary minus operator applied to
unsigned type, result still unsigned
1>..\sha1-lookup.c(316) : warning C4146: unary minus operator applied to
unsigned type, result still unsigned
the two lines of code are the same, and the message suggests a bad return
value:
#100: return -lo-1;
#316: return -lo-1;
Should these be protected by an appropriate brackets/calculation (-1-lo) ?
Or does
gcc use an alternate assumption about unary minus conversion for functions
returning int?
