From email explaining existence in the first place:
This is from before when the used checks throwing false
positives about unused due to changing the definition without
checking whether it *had* a value to begin with and me not
realizing they were false positives. I was thinking that it was
warning from ARGC et. al. not being used since the previous
macro or function call and the new value warning about
overwriting the old value.
Use a combination of response files and the archiver to support long
object file lists that do not fit in the Windows command-line length
limit. This can work only with GCC >= 4 because the MinGW GCC 3.x
front-ends do not support response-file syntax.
Commit 7a18dd8e (Add searching of variables, 2003-03-07) added method
cmCursesMainForm::JumpToCacheEntry to search for cache entries whose
names match a given search string. The method also had a useless
argument "int idx" probably left from earlier development iterations and
hard-coded in all calls to the value '-1'. The method compared this
argument to the "NumberOfVisibleEntries" member which at the time was of
type "int" also.
Commit ff1f8d0b (Fix or cast more integer conversions in cmake,
2010-06-29) changed the type of "NumberOfVisibleEntries" to size_t to
fix other integer conversion warnings. An unsigned type makes sense
given the purpose of the member. However, this caused the '-1' signed
value to be converted to a large unsigned value in the above-mentioned
comparison, leading to incorrect behavior.
Fix the problem by removing the useless argument and the comparison.

ed37fc3 VS2010: Set IntDir for utility and global targets.
e79e412 VS2010: Honor PROJECT_LABEL target property (#10611)
530ade6 Fix targets with . in the name for VS 10 IDE.
The new first arg in the test is the critical one
to prove that the new NMake specific code works.
The additional colons in the middle of the arg
stream work fine everywhere else, but not on
dash1.kitware with Visual Studio 7.1. Just avoid
the failure for now by removing the unnecessary
new args from the test.
VS2010 uses IntDir as the location for writing log files for
what happens during custom build steps. With no IntDir settings,
all ExternalProject usage within the same CMakeLists.txt file
would result in multiple utility targets all trying to use the
same custom build log files.
With parallel builds, they would try to use them simultaneously
and result in file access errors, preventing the builds from
completing successfully.
Now each utility target has its own IntDir setting, and so, its
own custom build rule log files.
