The size of the IBM GCC does define DEC128_EPSILON if __STDC_WANT_DEC_FP__ is defined by the user. This conditional on __STDC_WANT_DEC_FP__ is what TR 24732 specifies (at least, in the last draft I have; I don't have the final TR). Note that GCC does not support DFP on AIX, however, only on powerpc*-*-linux* | i?86*-*-linux* | x86_64*-*-linux* | s390*-*-linux* | i?86*-*-mingw* | x86_64*-*-mingw* | i?86*-*-cygwin*.
