    Make CPPFLAGS variables, as well as CFLAGS and LDFLAGS · 75cd9c50

    This fixes the "does unsetenv return void" test in the unix package on
    OS X, if I tell it to make 10.4-compatible binaries. The test uses
    CPPFLAGS but not CFLAGS, so it thought it returned int (as it was
    in 10.5-mode), but the C compiler (using CFLAGS, so in 10.4 mode)
    thought it returned void.
    I also added CONF_LD_OPTS_STAGE$3 to the list of things in LDFLAGS,
    which looks like an accidental ommission.
