Now, the argument to -stdpath is appended unconditionally to the search paths. There is probably good reason why there is a check, I'm not proposing to remove it. But maybe this is gives you a hint at where things go wrong. Somehow the check always fails on Windows, even if the directory exists, while it works fine on Linux.
thanks for the tests.
i think i found the cause of the problem: on w32 we cannot use "open()" to check whether a *directory* exists (which is what the "check_exists()" test boils down to).
here's what [msdn] says about he return values of open():
<snip> EACCES
Tried to open a read-only file for writing, file's sharing mode does
not allow the specified operations, or the given path is a directory.
</snip>
i've a working solution on my harddisk, that re-implements
check_exists(), but i'm unsure whether i should turn that into a public
function sys_exists() so it can be used in other places (e.g.
externals) as well...
