Thanks for working on this. I was going to try running a profiled kernel on -CURRENT and -STABLE to see what the difference was in time distribution. On -STABLE it built without a hitch. However, on -CURRENT I got the following even after doing a make clean: ../../../libkern/mcount.c: In function `mcount': ../../../libkern/mcount.c:91: `mcount_lock' undeclared (first use in this function) ../../../libkern/mcount.c:91: (Each undeclared identifier is reported only once ../../../libkern/mcount.c:91: for each function it appears in.) machine/atomic.h:141: warning: inlining failed in call to `atomic_cmpset_int' ../../../libkern/mcount.c:91: warning: called from here machine/atomic.h:234: warning: inlining failed in call to `atomic_store_rel_int' ../../../libkern/mcount.c:242: warning: called from here ../../../libkern/mcount.c: In function `mcount': ../../../libkern/mcount.c:91: `mcount_lock' undeclared (first use in this function) ../../../libkern/mcount.c:91: (Each undeclared identifier is reported only once ../../../libkern/mcount.c:91: for each function it appears in.) machine/atomic.h:141: warning: inlining failed in call to `atomic_cmpset_int' ../../../libkern/mcount.c:91: warning: called from here machine/atomic.h:234: warning: inlining failed in call to `atomic_store_rel_int' ../../../libkern/mcount.c:242: warning: called from here --- "Alan L.
