This requires frexpl and scalbnl which also don't currently exist.   
They have further dependencies.

What did work was a simple routine to call nextafterq in libquadmath.   
Quad and long double
are equivalent on hppa.

Then I thought I should create a long double port of libquadmath and  
integrate it into libgcc on hppa.
However, I haven't had time to complete this approach but it would  
provide a complete set of c99 long
double functions.
