Commit Message

  This is helpful for testing compat symbols in cases where _ISOMAC
is activated implicitly due to -DMODULE_NAME=testsuite and cannot
be disabled easily.

---
v2: Now actually tested in the situation where I need it.
v3: Dropped the __ mangling.  conform tests (and everything else)
    still pass, so it's apparently not necessary even for _ISOMAC.    
v4: Fix typo in comment
