+       if ${CXX-g++} $CXXFLAGS $CPPFLAGS -x c++-header conftest.h \
+               -o conftest.h.gch 1>&5 2>&1 &&

+          ${CXX-g++} -c $CXXFLAGS $CPPFLAGS conftest.C 1>&5 2>&1 ; then

Please use $glibcxx_CXX rather than $CXX (there's a comment in
GLIBCXX_CONFIGRE in acinclude.m4 explaining why, even though we set CXX
anyhow, odd...)
