Jon Turney c006fd459f makedoc: make errors visible 
Discard QUICKREF sections, rather than writing them to stderr
Discard MATHREF sections, rather than discarding as an error
Pass NOTES sections through to texinfo, rather than discarding as an error
Don't redirect makedoc stderr to .ref file
Remove makedoc output on error
Remove .ref files from CLEANFILES
Regenerate Makefile.ins

README 

This directory was an experiment to use floating-point operations to implement
the math library when a processor had a floating-point instruction set.  The
experiment was a failure in that some of the algorithms chosen (e.g. recursive
algorithms for sin/cos, etc..) are too simple and do not provide proper accuracy 
nor handle very large or very small inputs adequately.

The code is considered moth-balled.  The stable math library routines can be
found in libm/math and the configuration option to use this has been removed.

If you wish to experiment with the concept, please feel free and report back if
you have major improvements.
