libm: floorf() missing

[Peter Kjellerstedt]

Since no one seems to have answered this I will give it a shot.
 
The floorf() function is included in the math library if you enable
DO_C99_MATH in the uClibc configuration.
The L_* defines, e.g., L_floorf, are controlled by some make-magic in
libm/Makefile.in, and used to split one C file into multiple object
files.

	Hi,
	
	floorf() is apparently missing from libm. Grep'ing the source
code of a pretty recent checkout of uClibc, I have found an
implementation in libm/float_wrappers.c:
	
	#ifdef L_floorf
	libm_hidden_proto(floor) 
	float floorf (float x)
	{
	    return (float) floor( (double)x );
	}
	#endif
	
	However L_floorf is never defined and I was wondering if it was
not defined on purpose? Is it safe to enable this code or should we have
a different implementation? 
	
	Regards,
	Cedric Hombourger
