(j3.2006) Does C99 have an equivalent to HUGE?

[Van Snyder]

I have a C code in which gcc 4.4.0 on a Mac notices

e_float/efx/e_float_efx.h(57) : warning: integer constant is too large for 'long' type
e_float/efx/e_float_efx.h(58) : warning: integer constant is too large for 'long' type

The code in question is:
      static const INT64 ef_max_exp10    = static_cast<INT64>(+89999999999999999);
      static const INT64 ef_min_exp10    = static_cast<INT64>(-89999999999999999);

In Fortran, I'd probably use HUGE to initialize these constants.

Does C99 have an equivalent?
