That's weird, normally floorf is part of libm, and there is -lm.
But, according to:
http://www.gnu.org/software/gnulib/manual/html_node/floorf.html
it's missing on HP-UX 11.
In theory, you should be able to change all floorf into floor and it 
should work, but you might have some overflow issues.
A patch for this shall require some m4 configure tweaking and a few 
defines.
Another hack might be to use these:

#ifndef floorf 
#define floorf (float)floor 
#endif 

Find one .h which gets included in at least this .c :)

But honestly, I'm not happy with any solution (which are the same in 
fact, just 2 different ways to write it).
I let main coders decide what's the best way to do so, but this should 
help you go on with the compilation.

Kind regards,
