Update of /cvsroot/CMake/CMake/Tests/PrecompiledHeader
In directory public:/mounts/ram/cvs-serv13172/Tests/PrecompiledHeader
Added Files:

Log Message:
ENH: Added PrecompiledHeader test for MSVC compilers.
--- NEW FILE: foo_precompile.c ---
/* The foo_precompiled.h header is included by a /FI option when this
source is used to create a precompiled header. Include it here
explicitly to allow dependency scanning to detect the dependency
whether or not the include path is known to the scanner. */
