Update of /cvsroot/CMake/CMake/Source/kwsys
In directory public:/mounts/ram/cvs-serv10611/Source/kwsys
Modified Files:
CMakeLists.txt kwsysPlatformTestsCXX.cxx
Log Message:
BUG: Enable large files only if <cstdio> works
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.
