Re: [Integrit-devel] Fixing security/integrit build errors on sparc64

[Jos B. <jo...@ca...>]

See http://pointyhat.freebsd.org/errorlogs/sparc64-errorlogs/e.6.2005060522/integrit-3.02.00.log

gnupg/md5.c has:

    p = hd->buf;
  #ifdef BIG_ENDIAN_HOST
    #define X(a) do { *p++ = hd->a      ; *p++ = hd->a >> 8;      \
                      *p++ = hd->a >> 16; *p++ = hd->a >> 24; } while(0)
  #else /* little endian */
    /*#define X(a) do { *(u32*)p = hd->##a ; p += 4; } while(0)*/
    /* Unixware's cpp doesn't like the above construct so we do it his way:
     * (reported by Allan Clark) */
    #define X(a) do { *(u32*)p = (*hd).a ; p += 4; } while(0)
  #endif
    X(A);
    X(B);
    X(C);
    X(D);
  #undef X

I could be wrong but it looks like the BIG_ENDIAN_HOST case is broken (sparc64
is big endian); there, each occurrence of `hd->a' needs to be replaced with
`hd->##a' (i.e. use the paste operator). But I have no way of testing this.
