ikarus-errno.c needs a small change to compile on FreeBSD (possible patch included)

[Andrew Reilly]

FreeBSD doesn't do SysV STREAM, and so doesn't have the XSI-related errno values in errno.h. This is easy to work around, because made-up values are OK, because it doesn't look as though ikarus needs them anyway, and they won't be generated by the system. So this patch (or something like it) is all that I needed to get ikarus to compile on my FreeBSD/amd64 system. Nice work! I haven't used it in anger yet, but it seems to start up, and runs the benchmarks (with some errors and odd output...)
