I don't have djgpp -- my shell is 4DOS.

I don't have rm commands in my makefile, but when deleting 
intermediate files rm itself displays an "rm" command.

My question was about how this works, and the implications. Perhaps  
make simply deletes the files by an unlink( ) or similar function 
call and does a printf("rm %1", filename), or perhaps it's got some 
sort of internal rm emulator. If it's the latter, then I wonder what 
other commands are emulated.
