Build failure

[BERTRAND Joel <joel.bertrand%systella.fr@localhost>]

        Hello,

	I have seen some kernel patches since my last upgrade. Build 
distribution crashes with :

#   compile  libc/__cmsg_alignbytes.ln

/usr/src/src/sys/sys/mutex.h(155): redeclaration of kmutex_t [27]

*** Failed target:  __cmsg_alignbytes.ln

that seems to be related to fpulock into fpu_mtx conversion.

	I don't see anything false in 
/usr/src/src/../obj/destdir.sparc/usr/include/machine/proc.h or 
/usr/src/src/sys/sys/mutex.h and I don't have any idea to fix this bug.

        Regards,
