 #
 # On FreeBSD (and probably some others), clang++ does not meet an autoconf
 # assumption in identifying libtool configuration regarding shared library:
-# the configure script will execute "$CC -shared $CFLAGS -v -o" and expect
-# the output contains -Lxxx or -Ryyy.  This is the case for g++, but not for
-# clang++, and, as a result, it will cause various errors in linking programs
-# or running them with a shared object (such as some of our python scripts).

 # To work around this problem we define a temporary variable
 # "CXX_LIBTOOL_LDFLAGS".  It's expected to be defined as, e.g, "-L/usr/lib"
 # to temporarily fake the output so that it will be compatible with that of
 # g++.
