# We need AC_EXEEXT to keep automake happy in cygnus mode.  However,
# at least currently, we never actually build a program, so we never
# need to use $(EXEEXT).  Moreover, the test for EXEEXT normally
# fails, because we are probably configuring with a cross compiler
# which can't create executables.  So we include AC_EXEEXT to keep
# automake happy, but we don't execute it, since we don't care about
# the result.
