No, manifest don't give you permissions to write in to protected storage
automatically, user still should have rights for this. It stop
virtualisation, so your app get "acces denied" instead of write into
"crazy path".
I use manifest like yours and rc file like

#define MANIFEST 24
#define IDR_XPMANIFEST 1
IDR_XPMANIFEST MANIFEST "xpmanifest.xml"

It works for me in my old Borland apps, so IMHO it should works for you
in MinGW too.
