  Modified files:
    lib/msun/src         math.h 
  Log:
  Initial support for C99's (or is it POSIX.1-2001's?) MATH_ERRNO,
  MATH_ERREXCEPTION and math_errhandling, so that C99 applications at
  least have the possibility of determining that errno is not set for
  math functions.  Set math_errhandling to the non-standard-conforming
  value of 0 for now to indicate that we don't support either method
  of reporting errors.  We intentionally don't support MATH_ERRNO
  because errno is a mistake, and we are missing support for
  MATH_ERREXCEPTION (<fenv.h>, compiler support for <fenv.h>, and
  actually setting the exception flags correctly).
