On the subject of Linux, I tested the relative errors of the Linux 
versions of clog, casinh, etc.  They performed rather badly.  They 
really flunked the clog(z) for |z| close to 1 test.

As for your test program, maybe you could run some script to change the 
indents to the 8-char tabs when you are done.  It does sound like a 
useful program, and it would be nice if it were generally available in 
the FreeBSD source code.
