  24         Returns a readable string for an error number in errno.
  25
  26     INPUTS
  27         n - The contents of errno or a #define from errno.h
  28
  29     RESULT
  30         A string describing the error.
  31
  32     NOTES
  33         This function is used to override the strerror() function of
  34         stdc.library to handle the extra errnos from posixc.library.
  35         It is aliased as strerror() in libposixc.a
