Subject: sccmap.c: return an unsigned type from 'visit'
X-Git-Tag: 2.50.0~26^2~9

sccmap.c: return an unsigned type from 'visit'

Squashes a -Wsign-conversion warning.

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.
