Subject: Consolidate definition of current_directory
X-Git-Tag: binutils-2_39~1259
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c50e54825bfea1ab6afbd984a4d2e78e9306e70f;p=thirdparty%2Fbinutils-gdb.git

Consolidate definition of current_directory

I noticed that both gdbserver and gdb define current_directory.
However, as it is referenced by gdbsupport, it seemed better to define
it there as well.  This patch also moves the declaration to
pathstuff.h.  Tested by rebuilding.
