 6.3.3 Macros for compilers
 --------------------------
 
 Macros for compiler-related checks:
 
  -- Macro: KPSE_COMPILER_WARNINGS
      When using the (Objective) C/C++ compiler, set
      'WARNING_[OBJ]C[XX]FLAGS' to suitable warning flags (depending on
      the value given to or implied for '--enable-compiler-warnings').
      Call 'AC_SUBST' for them.  At present this assumes GNU compiler
      warning options, but could be extended to others if necessary.
 
      This macro caches its results in the 'kpse_cv_warning_cflags', ...
      variables.
 
  -- Macro: KPSE_COMPILER_VISIBILITY
      When using the C or C++ compiler, try to set
      'VISIBILITY_C[XX]FLAGS' to flags to hide external symbols.  Call
      'AC_SUBST' for this variable.  At present this only tests for the
      compiler option '-fvisibility=hidden', but could be extended if
      necessary.
 
      This macro caches its results in the 'kpse_cv_visibility_cflags' or
      'kpse_cv_visibility_cxxflags' variable.
 
  -- Macro: KPSE_CXX_HACK
      Provide the configure option '--enable-cxx-runtime-hack'.  If
      enabled and when using 'g++', try to statically link with
      'libstdc++', notably improving portability of the resulting binary.
 
      This macro caches its result in the 'kpse_cv_cxx_hack' variable.
