  Log Message:
  -----------
  Support Visual C++ 2.0 and 4.0 toolsets by using wsock32.dll instead
of ws2_32.dll. This might be put back for ipv6 support, but it might
not since it looks like the headers use LoadLibrary/GetProcAddress for
that.

  Log Message:
  -----------
  Support for bootstrapping from the cm3-5.1.3 release,
which must have been built with Visual C++ 4.0, or maybe
4.1 or 4.2. 4.0 in particular (4.1/4.2 unknown) output
floating point division that requires Pentium fdiv
workaround in the C runtime, that is missing in newer
C runtimes.

Put this in sysutils instead of where I was previously
considering, a new LibcCompat package.

This is only needed for bootstrap, not for everything.
i.e. when using an old m3core.

The floating point division is in dtoa.c, which
maybe should be in Modula-3. "None" of the backends
generate this code -- well, the C backend with
old C compiler would.

but no real change or fix. i.e. using old static libs with new
compiler/runtime.
