[tlbuild] Problems with asy-1.96 on FreeBSD: no log(2), needs explicit "#include <cstdio>"

[Nikola Lečić]

Hello,

I've just built asy-1.96 with gcc-4.4 on FreeBSD, but I had to apply
this against the sources (the actual errors are given below). Is this
log2() definition suitable for asy?

The math(3) says:

BUGS
     The log2() function is missing, and many functions are not available in
     their long double variants.

System: FreeBSD-7.2/amd64.
