Not true: C99 requires a long long type. And your claim is not true of real-world LP64 systems. E.g. x86_64 (aka amd64) versions of Linux, Solaris, FreeBSD and Mac OS X all have 64-bit long long (and not just with gcc). So does 64-bit Sparc Solaris. I am speaking of C here: a far-too-common error is for C++ programmers to assume that long long is part of C++, but it is not in the 1998 standard and careful compilers report it as a warning or even error. > > Earnie. > > ------------------------------------------------------------------------------ > What Every C/C++ and Fortran developer Should Know! > Read this article and learn how Intel has extended the reach of its > next-generation tools to help Windows* and Linux* C/C++ and Fortran > developers boost performance applications - including clusters. > http://p.sf.net/sfu/intel-dev2devmay > _______________________________________________ > Mingw-w64-public mailing list > Mingw-w64-public@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/mingw-w64-public > -- Brian D.
