The underlying C code for the Windows C RTL is probably on a server in
a bunker in Redmond WA ... good luck :-)

Perhaps you could start lashing up something along the lines that Dan
mentioned, e.g.

floated = {
   'NaN': 1e1000 / 1e1000,
   'Inf': whatever,
   }.get

def myfloat(s):
   try:
      return float(s)
   except:
      value = floated(s)
      if value is not None:
          raise
      return value

Then when/if your mapping has enough entries to make it worthwhile,
you could maybe suggest that this be done in Numpy or in the Python
core.
