MiNT 1.12: a few bug fixes

[Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>]

Here is a patch that fixes a few bugs in MiNT 1.12:

- biosfs.c: always use case insensitive comparison on file names
- dosdir.c (d_delete): don't change anything until everything has been
  verified
- mem.h: parenthesize argument in the ROUND macro to make it robust
