Check Text ( C-33733r3_chk )
Using Windows Explorer, search the system for the existence of known compilers such as msc.exe, msvc.exe, Python.exe, javac.exe, Lcc-win32.exe, or equivalent. Look in all hard drives. Also, query the SA and the Web Manager to determine if a compiler is present on the server. Query the SA and the Web Manager to determine if a compiler is present on the server. If a compiler is present, this is a finding. NOTE: When Apache is part of a suite install, e.g. application server, and a compiler is needed for installation and patching of the product, document the installation of the compiler with the ISSO/ISSM and verify that the compiler is restricted to administrative users only. If documented and restricted to administrative users, this is not a finding.

Fix Text (F-29368r3_fix)
Remove any compiler found on the production web server. If the compiler is needed to patch the product in a production environment, document the compiler installation with the ISSO/ISSM and ensure that the compiler is restricted to only administrative users.
