the long double is supported as 96-bit floating point for gcc. This isn't as ms_abi declares it, but I follow here the 32-bit port. So we allow higher precision, and by vendor specific headers it has not much affects, beside that the vendor specific scanf/printf functions can't print it proper. Therefore the mingw runtime provides C99 compliant (and gnu-style compiant) alternatives to print/scan them. I am verifying it at the moment for w64 target, if we have here same issues. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39224
