AIX indeed produces this output.

AIX additionally, for the call
  strfmon (buf, sizeof (buf), "%.2n", 123.5);
produces the result
  "12350"

So, this implementation of strfmon is very standards-compliant.
But without a distinction between positive and negative values,
and without a visible decimal separator, this behaviour is useless,
or even dangerous (if a programmer was not aware of this behaviour
and has not worked around it).

I would vote for removing strfmon() and strfmon_l() from POSIX.
