0.8.10.41:
	Fix BUGS 280 and 312: no more bogus duplicate warning
	definitions.
	... it appears that one cannot distinguish between XEPs for the
		various different purposes;
	... and I don't propose to try to make it possible...
	... so alternative strategy: make DEFUN check for it.  Less
		hi-tech, but also less broken.
	... alter %COMPILER-DEFUN again to distinguish between
		:COMPILE-TOPLEVEL uses and non-:CT.
	... means another change in fasl file version.
	... more test cases.
