     25 dnl sort alphabetically after any libtool, autoconf or automake
     26 dnl provided .m4 macro file that might get copied into this same
     27 dnl subdirectory. This allows that macro (re)definitions from this

     34 dnl unnecesary C++, Fortran and Java tests when only
     35 dnl using C language and reduce resulting configure
     36 dnl script by nearly 300 Kb.
