## If both a non-* glob and a * match, non-* wins.
## This is GNU linkers' behavior. We don't feel strongly this should be supported.
# FOO: GLOBAL DEFAULT 7 foo@@foo

# BAR: GLOBAL DEFAULT 7 foo@@bar

## When there are multiple * patterns, the last wins.
# BAR2: GLOBAL DEFAULT 7 foo@@bar2
# DUPWARN: warning: wildcard pattern '*' is used for multiple version definitions in version script
