Oh...loading hypergeometric twice eliminates the rtest_hg bugs. These bugs
might be unique to my setup or to Clozure CL. Maybe somebody with
CVS Maxima can try this experiment:
$ ./maxima-local
Maxima 5.18post http://maxima.sourceforge.net
Using Lisp Clozure Common Lisp Version 1.4-dev (WindowsX8632)
(%i1) load("hypergeometric")$
;Compiler warnings :
; In 2F1-NUMERIC: Unused lexical variable MAXIMA::$MULTIPLE_VALUE_RETURN
(%i2) hypergeometric([1/2,1],[3/2],2807.0);
BIGFLOAT: Unable to convert false to a CL or BIGFLOAT number
-- an error. To debug this try debugmode(true);
(%i3) load("hypergeometric")$
(%i4) hypergeometric([1/2,1],[3/2],2807.0);
(%o4) 3.5629454083782787E-4 - 0.0296482231479244 %i
(%i5)

P.S. Trivia: Why 2807?
