[Bug java/16472] New: jartool.c uses ftruncate, nonexistant on mingw32

[aaronavay62 at aaronwl dot com]

The recent patch here:
http://gcc.gnu.org/ml/java-patches/2004-q2/msg00441.html

causes bootstrap to fail on i686-pc-mingw32 because MinGW lacks the non-C-
standard POSIX function ftruncate.  It does, however, have a function named 
_chsize prototyped in <io.h> with compatible parameters and similar semantics.

I'm submitting a bug report rather than a patch because I'm not exactly sure 
how what the most appropriate method of fixing this is.

Exact errors follow:

This bootstraps and appears to work correctly on my i686-pc-mingw32
installation.  Sorry for the delay; only so many cycles to go around.
