I get a warning (treated as an error) when I compile on Debian Lenny

This seems to work on Fedora Core 15 with gcc 4.6.0.
I'm not sure if my system config or the code is at fault. truncl isn't
defined anywhere in /usr/include/* except for C++ header files.
Apparently, it's a gcc builtin function. I have no idea what parameters
it expects. You're passing it long doubles, this is in line with the
manpage.
If I enable your define for windows
#define truncl(ld) floorl(ld)
things work ok for me. Should that be enabled for older gccs as well or
are you aware of gcc settings that make it define truncl() in the standard
way?
Best regards,
Martin
