        If we don't have Cyg_ErrNo, just use a cyg_int32 instead, to

        make sure that the fields are still correct for the input

        test vector.

        In doTestVec(), before checking errno, check if we're

        in IEEE mode (either compiled in or set at runtime) because if

        so, and errno is set in the errno field of the input test

        vector, then we have to skip this, since we can't validate the

        output.

        In all modes, if errno is set in the input test vector, don't

        bother checking the actual values

        and errno will only be available if the C library is present.

Mon Jul 27 22:45:01 1998  Jonathan Larmour  

        * tests/vectors/vector_support.h (checkErrorAcceptable):

        Add extra check for tolerance acceptance so it behaves correctly with

        underflow and overflow

        Also reverse sense of checkErrorAcceptable() so it now returns

        false on success and true on failure, as suggested by hmt. Change

        this in doTestVec() (which is where it is called) too.

        Add new CYGFUN_LIBC_matherr config option to prevent inclusion of

        default matherr

Mon Jul 20 18:07:31 1998  Jonathan Larmour  

        * src/misc/infconst.c:

Thu Jul 16 20:07:26 1998  Jonathan Larmour  

        * include/math.h, include/sys/ieeefp.h, src/misc/infconst.c:
