[CMake] 2.4.7 testsuite failures on Tru64 UNIX 5.1

[Albert Chin]

Built cmake-2.4.7 on Tru64 UNIX 5.1 with the following:
  % cc -V      
  Compaq C V6.5-303 (dtk) on Compaq Tru64 UNIX V5.1 (Rev. 732)
  Compiler Driver V6.5-302 (dtk) cc Driver
  % cxx -V
  Compaq C++ V6.5-042 for Compaq Tru64 UNIX V5.1 (Rev. 732)
  Compiler Driver V6.5-042 (cxx) cxx Driver

  % gtar zxf cmake-2.4.7.tar.gz
  % cd cmake-2.4.7
  % CC=cc CXX=cxx ./bootstrap -verbose
  % gmake VERBOSE=1
  % gmake test VERBOSE=1
  ...
  26% tests passed, 49 tests failed out of 66

Anyone else seeing this? I tried rerunning one of the tests in verbose
mode:
  % bin/ctest --force-new-ctest-process --extra-verbose \
  --tests-regex CommandLineTest

Any idea how to resolve this?
