Remove buildfiles: win32/*.dll win64/*.dll We're autobuilding these from maintained sources.
libcurl 7.71.1
libcurl-4.dll (7.70.0.0) with support for http2
libcurl-4.dll - 7.70.0.0
mark libcurl-4.dll unexecutable (means nothing to Windows, but I know it needs to be rebuilt)
buildfiles: rename dir from w32 to win32
