    Now we traverse recursively for test-*.sac files in subdirectories,
    and add them as tests.  When we run the test, we cd into the
    $(dirname) of the test, generate makefile as previously, and run
    the makefile.  We pass -I to the make call and -cppI to the sac2c
    call.

    - test-condfun.nostdlib.sac.

    This is a first example on using gtest for testing individual
    aspects of traversals.  This isn't yet perfect, but it is a
    good starting point.

    Otherwise, C++ emmits a warning that conversion from
    (const char *) to (char *) is not allowed.

    Some of the tests do not pass, as there are bugs in the
    implementation of string functions.
