From the option documentation of VS >= 7.1:
"In earlier versions of Visual C++, the compiler used several discrete
heaps, and each had a finite limit. Currently, the compiler dynamically
grows the heaps as necessary up to a total heap size limit, and requires
a fixed-size buffer only to construct precompiled headers. Consequently,
the /Zm compiler option is rarely necessary."

Change test if DEL key is allowed from 'curcol > 0' to 'curcol >= 0', as
deleting forward is reasonable in the first column (and probably
expected by users to work).
Support for DEL was first added in commit b3b43508 (BUG: fix for 6462,
delete key should delete the current char, 2008-08-19). The commit
appears to have copied the original logic from the backspace code so the
old 'curcol > 0' logic was accidental rather than intentional.
The performance feature of only performing a git fetch when needed
during the ExternalProject update step is verified during the test.
A fetch is identified by removing the FETCH_HEAD file and checking for
its reincarnation.
This prepares the numberous tests that occur in the ExternalProjectUpdate
test. The tests were passing previously because a fresh build was not performed.
Tests are added for UPDATE_COMMAND to ensure it is working properly. Testing
infrastructure is added along with tests for Git, but tests for other version
control systems could easily be added in the future.
The warnings are enabled for now only when using GCC 4.2 or later.
It may be possible later to also enable them when building CMake
with clang. Don't duplicate the compiler flags if already set.
This is not ambiguous to the compiler, but it may seem ambiguous to
the reader.
From reading 3a53005f (Build object library targets in VS), 5484550a
(Detect and set Unicode character set in VS 10), and 9e01aefd (VS:
Add support for WinRT project properties (#12930)), this appears to
be the intentional semantic.
Build a shared library and an executable linking to it inside the inner
test. Set LINK_DEPENDS_NO_SHARED on the executable. Add a custom
target to compare the output file times. Verify that on the first build
the executable is newer than the library. Then modify a library source
file. Verify that on the second build the library is newer because the
executable did not have a dependency to re-link.
