Alexander Neundorf 512e0d40ef ENH: set UNIX, WIN32 and APPLE in cmMakefile.cxx as it was before, so it
works for scripts, then reset them in CMakeSystemSpecificInformation.cxx, so
the platform modules can set them again for the target system

# This file is included by cmGlobalGenerator::EnableLanguage.
# It is included after the compiler has been determined, so
# we know things like the compiler name and if the compiler is gnu.
# before cmake 2.6 these variables were set in cmMakefile.cxx. This is still
# done to keep scripts and custom language and compiler modules working.
# But they are reset here and set again in the platform files for the target
# platform, so they can be used for testing the target platform instead
# of testing the host platform.
