c.lib 1.169 (8.8.2004)

- Since the 'long double' data type is not really supported by the GCC
  versions we use (and not supported by SAS/C either) building the
  library with support code for it is now a configurable option. Unless
  enabled, 'long double' is now treated like 'double'.

- Reworked the HUGE_VAL definition which previously would default to
  Infinity. The new code properly defines this to the largest
  representable floating point number. The 'great' thing about the
  HUGE_VAL definition in this library is that it's a reference to
  a binary constant initialized by the library startup code. So any
  application checking for HUGE_VAL merely needs to be relinked
  rather than recompiled.

- Ditched __is_infinity() and __is_not_a_number(), brought them back
