* Noteworthy changes in release 2015.02.04 (2015-02-04) [stable]

  AX_OPENMP: Test that we can actually #include <omp.h> successfully.

  AX_COMPILER_FLAGS was re-factored into AX_COMPILER_FLAGS_CFLAGS and
  AX_COMPILER_FLAGS_LDFLAGS.

  AX_CODE_COVERAGE detects gcov program.

  AX_VALGRIND_CHECK now supports running without libtool.

  AX_GCC_VERSION was improved.

  Re-factored and modernized the macros AX_CXX_TEMPLATES, AX_CXX_CONST_CAST,
  AX_CXX_COMPLEX_MATH_IN_NAMESPACE_STD, AX_CXX_BOOL, AX_APPEND_FLAG,
  AX_CHECK_*_FLAG, AX_CHECK_ENABLE_DEBUG, and
  AX_CXX_DEFAULT_TEMPLATE_PARAMETERS.

  AX_CXX_COMPILER_VENDOR was deprecated in favor of AX_COMPILER_VENDOR.

  AX_HAVE_OPENGL was deprecated in favor of AX_CHECK_GL, AX_CHECK_GLU,
  AX_CHECK_GLUT, and AX_CHECK_GLX.

  AX_CHECK_GL has a new parameter --with-mesa that allows choosing the order of
  opengl lib detection.

  Portability of AX_LUA was improved. Support for LUA 5.0 was added.

  New macros AX_IS_RELEASE, AX_COMPILER_FLAGS_GIR, AX_CXX_ERASE_ITERATOR_TYPE,
  AX_COMPILER_VERSION, AX_CHECK_GLX, AX_CHECK_VSCRIPT, AX_VALGRIND_CHECK,
  AX_PKG_CHECK_MODULES, and AX_COMPILER_FLAGS were added.

  AX_PROG_FLEX: Also accept gflex.

  AX_LIB_HDF5: remove extra leading space from include path flag. That space
  creeps into HDF5_CPPFLAGS and breaks the include path flag into two tokens,
  e.g., "-I" and "/usr/include". While this may be legal and \ 
doesn't affect the
  compilation, it does break some library tools (e.g., when the macro is used
  in building a dynamic library that uses pkg-config).

  AX_PERL_MODULE_VERSION: use more portable syntax for shell arithmetic.

  AX_JNI_INCLUDE_DIR: support standard Oracle JDK installation layout on Mac OS
  X.

  AX_PROG_JAVAH_BIN_DIR: fix misspelled variable name and follow javah symlink
  to find jni.h.

  AX_BOOST_PYTHON: use unique names for local variables
