[bug #51311] Checking search retries for implicit make rules

[Paul D. Smith]

Update of bug #51311 (project make):

                  Status:                    None => Duplicate              
             Open/Closed:                    Open => Closed

Follow-up Comment #3:

As pointed out on the mailing list, it's not true that there can only be one
prerequisite containing the pattern character (%).  In fact there can be zero,
one, or as many prerequisites containing the pattern character as you like. 
Essentially if the target contains a pattern character then it's a pattern
rule: the prerequisites list doesn't matter.

As Mike points out, the reason your example doesn't work is that a pattern
character must match at least one character.

As for allowing pattern characters to match zero characters, that is already
filed as an enhancement request as bug #29448 so we don't need another one.
