--- Comment #5 from Ryan S. Arnold <rsa at us dot ibm.com> 2011-12-09 16:03:04 UTC --- As a temporary fix I've added the following to libdfp: http://www.eglibc.org/cgi-bin/viewvc.cgi/libdfp/trunk/dfp/float.h?view=markup This adds <dfp/float.h>, which does #include_next <float.h>, and then checks to see #ifdef __cplusplus and #ifndef _Decimal64. If both pass, then it means that the compiler has not yet added _Decimal[32|64|128] compatibility support to float.h and it defines them itself.
