Subject: sccmap.c: use another unsigned type to squash -Wconversion warnings
X-Git-Tag: 2.50.0~26^2~12

sccmap.c: use another unsigned type to squash -Wconversion warnings

The `val` member of `Agnodeinfo_t` is unsigned and all uses of this function
store the return value in an unsigned. So it seems this function always should
have been declared as returning an unsigned.
