I'll take a look at this in an hour or two. I'll restrict the testing to the
Xeon machine, as it is a zillion times quicker than the old SPARCs.
What comes to my mind, is that perhaps 'copysign' is only defined in C99.
Solaris header files are pretty strict about what gets defined and not defined
depending on the mode of compilation. The compiler option -std=c99 is not being
passed yet the man page for copysign on my OpenSolaris laptop (yet another
system) says:
drkir...@laptop:~$ man copysign
