Patch: DIR_SEPARATOR usage in jcf-write.c and jcf-io.c

[Ranjit Mathew <rmathew at hotmail dot com>]

Hi,

    This is a resubmission of the DIR_SEPARATOR patch for jcf-io.c 
and jcf-write.c in the front-end.

The last time I had submitted this, it was suggested that we 
might be able to use something from libiberty instead - AFAICT, 
the only relevant functions in libiberty seem to be the 
basename( )/lbasename( ) functions. AFAIK, if we are to use them, 
the code will still be as "untidy" as this, as they do not 
directly address the issue we are trying to resolve here.

This patch resolves the bug on Win32 where "gcj -C foo\Bar.java"
produces the class file in the current directory instead of in
"foo" while "gcj -C foo/Bar.java" has the correct behaviour.

Ranjit.

	* jcf-io.c (caching_stat): Account for both DIR_SEPARATOR
	and DIR_SEPARATOR_2 for a target.
	Correct minor typos.

	* jcf-write.c (make_class_file_name): Take both DIR_SEPARATOR
	and DIR_SEPARATOR_2 for a target into account.
