The 'binary' openmode does not exist on all compilers. We define macro
<kwsys>_ios_binary, where <kwsys> is the KWSys namespace, to refer to
std::ios::binary if it exists and 0 otherwise. Sample usage:
kwsys_ios::ifstream fin(fn, kwsys_ios::ios::in | kwsys_ios_binary);
Some AIX/gcc version combinations the <cstdio> header breaks when large
file support is enabled. See this GCC issue for details:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20366
We work around the problem by enhancing the configuration check for
large file support to include <cstdio> when available. This will cause
LFS to be disabled when the above problem occurs.
