dnl @synopsis FH_HAVE_STL
dnl 
dnl We look for an STL (standard template library). An include path
dnl to the STL can be given as a parameter.
dnl
dnl We need the bool datatype. There are already some macros that detect
dnl boolean types, but we have to be consistent with the STL found. We
dnl check for two files: stl_config.h and bool.h. Since we assume that
dnl an STL is present, one of these files must be present, too. Including
dnl one of these files automatically defines bool.
