Quick fix to allow "make" to work when compiling pak128 (outdated Makefile failed on grounds.outside). Seems to work now, and noticed another couple of folders that weren't included but I've not fully tested end pak to double check that absolutely everything has been compiled.
Ok. done more checks and there were still a few folders missed - this seems to cover all them all.
thanks for fixing the Makefile. it is very useful to have it, saves a lot of time since not the whole pak has to be rebuilt every time a small change is made.
Applied in r1274 - thank you!
