Either that, or you could also AC_CONFIG_FILES([tests/defs])
and define COMPILE='@LIBTOOL@ --mode=link @CC@ ...' in
(Maybe write it in a way that it uses $CC if its defined.)
I've used both.

Sometimes, I also find easier not to use `CHECK = ... ' tests,
and call your test case directly from a local rule.  For
instance I have a test case I like to run in my projects to
check that all installed headers files are self-contained (i.e.,
they include anything that needs to be included) and properly
guarded against multiple inclusions.  The check actually tries
to compile the header, so it needs $CXX and friends.  Also I
want to run it on the source tree during "make check" and on the
installed headers during "make installcheck"; so I used some
variable, $INCDIR, to specify the directory to check.

        CXX='$(CXX)' \
        INCDIR='$(top_srcdir)/src' \
        $(SHELL) $(srcdir)/includes.test

        CXX='$(CXX)' \
        CPPFLAGS='-I$(includedir) -I$(pkgincludedir) $(LIBGSPN_CPPFLAGS) $(CPPF
LAGS)' \
        INCDIR='$(pkgincludedir)' \
        $(SHELL) $(srcdir)/includes.test
