# As of the writing of this demo, GNU Autoconf's AC_OBJEXT and
# AC_EXEEXT macros only works for C compilers!
# Libtool's setup macro calls AC_OBJEXT and AC_EXEEXT without setting
# the test language to C.  We do it before any libtool setup macros are
# called so that the proper values are cached beforehand.  We also do
# it before any linker flags (LDFLAGS) are set so that C++ specific
# ones don't break the tests.
