That's gotten rid of most of the warnings, but there are several still 
hanging around in the smaller lib subdirectories where there seem to be 
".in" files that are translated upon ./configure.  Try

grep DBL_EPSILON */*/*
(There are a few .cc files)

grep DBL_EPSILON */*
(There are many .cc files and a few .in files)

grep FLT_EPSILON */*
(Just a couple .in files)
liboctave/Quad-opts.in:  INIT_VALUE = "::sqrt (FLT_EPSILON)"
liboctave/Quad-opts.in:  INIT_VALUE = "::sqrt (FLT_EPSILON)"

All the rest looks like C code.
