Yep, I know, and I intend to fix the problem by having an
implementation of isnan*() in libc and libm.  (It needs to be in
each, for different reasons.)  The commit you responded to is
actually related to fixing some slightly different source/binary
compat problems; it was another commit that caused the breakage.
The trouble is that there's a lot of cruft we need to support
because we never bump libm's version number.  We have to be able
to link *any* of{2,3,4,5} with, we need to
support programs compiled with the 4.x math.h running with the
5.X, etc.

As I said before, I'll try to look into it tonight.  But at the
moment, I have a lot going on in my day job...
