Why does this test link against libsystemc.a ? It looks like you are
adding it to LIBS or LDFLAGS, right?

If so, don't do it. Instead write your own test to check for libsystemc.a.
Ideally you could use AC_CHECK_LIB([systemc],[main]). If that does not
work, just write this test by hand (generate file with empty sc_main(),
compile, link against -lsystemc).

Hope this helps.
