[Live-devel] No fabsf() on Solaris 9 and older

[Sergio Gelato]

While it appears that Sun has finally added fabsf() to <math.h> in Solaris 10,
some of us still need to build for earlier versions.

The following patch replaces fabsf() with fabs(); if my understanding of C++
isn't completely wrong, this shouldn't have any adverse impact on the results.
(Solaris 8 with patch 111721-04 has
	extern float __fabsf(float);
        inline float fabs(float __X) { return __fabsf(__X); }
in the relevant header file.)
