On Solaris 8, I'm seeing these errors:
../gllib/math.h:816: error: 'truncf' was not declared in this scope
../gllib/math.h:835: error: 'trunc' was not declared in this scope
This fixes it, by using the simpler idiom for a missing function.

math: Fix some C++ test errors on Solaris 8.
* lib/math.in.h (truncf, trunc): Use simpler idiom.
