Since Debian installs on a variety of platforms, I can report that the
compilation and unit test of iausofa_c succeeds at least on the
following platforms:

Linux
=====
* amd64, i386, ia64
* alpha
* PowerPC 32 and 64 bit
* arm little endian with and w/o FP emulation
* mips big & little endian
* IBM zSeries direct and userland (s390/s390x)
* SuperH RISC 

Other
=====
* Hurd on i386
* KFreebsd (BSD kernel with Debian userland) on i386 and amd64

Contrary to the original code, we build a shared library. No compilation
has failed so far. Sure, the environment is always Debian (and the
compiler is gcc), but the system architectures vary heavily, and I would
have a good feeling about the portability of the code.
