    Add .rcpp files to .gitignore.
    
    This should have been done months ago in commit bf0cf984c, but I've
    been indecisive about whether to keep my local dev builds in the
    windows subdirectory itself or one level further down...

    Correct the comment in mpint_i.h.
    
    At some point in mpint.c development I switched the main macro defined
    by the ifdefs from BIGNUM_INT_BITS to the new BIGNUM_INT_BITS_BITS, so
    I could loop from 0 to the latter in safe bit-shift loops that test
    each bit of a shift count. But I forgot to change the comment
    accordingly.

    Allow command-line override of the BignumInt type.
    
    This makes it easy to re-test the mpint functions using different word
    sizes and smoke out any more confusions between integer types in
    mpint.c, by recompiling with -DBIGNUM_OVERRIDE=4 or =5 or =6 (for 16-,
    32- or 64-bit respectively).
    
    BIGNUM_OVERRIDE only lets you force the size downwards, not upwards:
    of course the default behaviour is to use the largest BignumInt the
    ifdefs can find a way to, and they can't magic up a bigger one just
    because you tell them you'd like one.

    mpint: fix further integer-type confusions.
    
    This makes the test suite pass if I compile with -DBIGNUM_OVERRIDE=4
    to fall back to 16-bit BignumInt. In that mode, BignumInt is smaller
    than 'int', which means default promotion keeps causing things to get
    promoted to 'int' unexpectedly, so I had to add some casts back down.
