To elaborate on this: if you want to produce binaries compatible with
old Linux systems, it is pretty much necessary to build on such an old
Linux system, because otherwise you'll get bitten by glibc ABI issues
(not to mention libstdc++, but at least you can link libstdc++
statically).

Windows has no such problem: you can redistribute a recent MSVCRT DLL
on an old Windows system.

Antoine.
