I think following is more safe. I think we should exclude other error codes
except EEXIST ( I tested that I'm getting this code even if there is directory
or R/O file with conflicting name, so all worked Ok). I'm didn't make patch
for tempnam() as I don't need it currently. 

Looks that these procedures are working correctly together with others
from djdev201 so I'm not going now to change to djdev202 fully. Perhaps
I'll combine necessary procedures from 202 in one file (together with some
modifications especially for gcc) and use it as additional module for building
gcc (no more such ugly hacks as I talked before)
