after a few weeks of efforts to set up a djgpp environment on a new 
computer, i came up to the following conclusions:
under freedos, i have experienced various i/o failures, especially with 
the more advanced features, like fat32, disk caching and lfn.
under drdos, i could not use those most advanced features, but the 
infrastructure seems to be more stable. extended memory support is very 
limited, so i am using qemm. the command interpreter is also a little 
buggy, but could be replaced by bash.
the most reliable dos version i have used with djgpp is, i have to 
admit, msdos 6.22. msdos that comes with windows 95 and 98 has built in 
dpmi, which does poor memory protection, as compared to cwsdpmi.
as a free software developper, i'm using drdos 7.03 on a fat16 disk, no 
doslfn, , with qemm, ramdrive, but no disk cache, since nwcache, that 
comes with drdos, is generating some file locating errors.

hope to be helpful,

alex
