#1925 compile warning in TkCanvas.c

[Bob Techentin]

My (particularly picky) HP compiler issues this warning
on tkCanvas.c

cc:
"/sppdg/scratch/bob/temp/tk8.4.11/unix/../generic/tkCanvas.c",
line 214: warning 558: Empty declaration.

Apparently the semicolon doesn't belong on this line:

TCL_DECLARE_MUTEX(typeListMutex);

thanks for testing

I fixed this before on HEAD,
but missed it in 8.4.

RC5 will have this corrected.
