Fixed in r10-7424. GCC's poutput is now as expected:
$ gcc -O2 -S -Wall -Wmismatched-tags -Wredundant-tags pr94078.C
pr94078.C:2:8: warning: redundant class-key ‘class’ in reference to ‘struct
S<int>’ [-Wredundant-tags]
2 | extern class S<int> si; // missing -Wmismatched-tags
| ^~~~~

pr94078.C:3:8: warning: redundant class-key ‘struct’ in reference to ‘class
S<int>’ [-Wredundant-tags]
3 | extern struct S<int> si; // bogus -Wmismatched-tags

pr94078.C:2:14: warning: ‘S<int>’ declared with a mismatched class-key ‘class’
[-Wmismatched-tags]
2 | extern class S<int> si; // missing -Wmismatched-tags

pr94078.C:2:14: note: replace the class-key with ‘struct’
