PATCH mingw32 Changes to allow mainline to bootstrap.

["Aaron W. LaFramboise" <aaronraolete36 at aaronwl dot com>]

The two patches below need to be applied to allow mainine to bootstrap 
on i686-pc-mingw32.  In addition, the patch discussed at 
http://gcc.gnu.org/ml/gcc-patches/2004-05/msg01610.html needs to be 
applied as well.  Until any general mechanism is adopted to 
opt-in/opt-out platforms from libmudflap, or support is implemented for 
mingw32, I think its reasonable that the build do the right thing by 
default.

Patch #1:

vfail in libbanshee/engine/util.c calls fflush(stdin), as well as
sync(), and fsync() for each of the standard file descriptors.
In addition, fflush(stdin) is undefined, and sync() and fsync()
are not portable.  I don't think, in the general case, any of
this is necessary to ensure the streams will be printed.

  * engine/util.c (vfail): Remove unnecessary sync, fsync, and fflush.

Patch #2:
Fixes this warning for mingw.  While I realize this code may disappear 
entirely, I think it would be nice if GCC were able to bootstrap until 
that happens.
