Subject: Turn some windows-nat.c static functions into methods
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=551765020680c23de7641577e72d88083c50194d;p=binutils-gdb.git

Turn some windows-nat.c static functions into methods

This patch turns some windows-nat.c static functions into methods on
windows_nat_target.  This avoids having to reference the
windows_nat_target singleton in some more spots -- a minor code
cleanup.
