Summary0011503: cmake fails to remove non existent file
Descriptioncmake spuriously fails to remove files which it has produced during "try compile" with error "No such file or directory". Since the file does not exist anymore, I think this should be reported as a success to remove the file.
Steps To Reproducecmake -G "Visual Studio 9 2008 Win64"
-- Check for working C compiler: cl
-- Check for working C compiler: cl -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: cl
-- Check for working CXX compiler: cl -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detected 64-bit platform.

-- Looking for sys/types.h
CMake Error: Remove failed on file: C:/club/bzr_mysql-5.1-telco-7.0/1019/mysql-5.1.51-ndb-7.0.21-pb1019/CMakeFiles/CMakeTmp/Debug/cmTryCompileExec.exe: System Error: No such file or directory
Additional InformationLooking in Source/cmCoreTryCompile.cc I see a retry loop which retries the RemoveFile() 5 time with half a second delay. Would suggest that the loop is extended to also check if file still exists.

Maybe something like below?

cmake-2.8.3$ diff -u Source/cmCoreTryCompile.cxx Source/cmCoreTryCompile.cxx.orig
