Subject: gdbsupport: Use LOCALAPPDATA to determine cache dir
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=60a7223fdd196d540f87504833166f558c95c035;p=binutils-gdb.git

gdbsupport: Use LOCALAPPDATA to determine cache dir

Use the LOCALAPPDATA environment variable to determine the cache dir
when running on Windows with native command line, otherwise nasty
warning "Couldn't determine a path for index cached directory" appears.
