Re: Bug in AC_PROG_F77_C_O ??

[Steven G. Johnson]

This certainly does look like a bug.  However, AC_MSG_RESULT should not
be needed because the AC_CACHE_CHECK should already have printed out the
result.  I would suggest the following simpler patch instead:

2001-03-13  Steven G. Johnson  <address@hidden>

        * aclang.m4 (AC_PROG_F77_C_O): define F77_NO_MINUS_C_MINUS_O
        when test fails, not when it succeeds(!).
