                } while(sn < sscop->vr_h && !QFIND(&sscop->rbuf, sn));
                                             ^
sys/contrib/ngatm/netnatm/saal/saal_sscop.c:173:4: note: expanded from macro 'QFIND'
                        break;                                          \
                        ^
1 error generated.

The idea is to remove any ambiguity by replacing the macro with an
equivalent static inline function.
