function.c, unlink, copy

[Torsten Mohr]

Hi,

i often use "rm -f" OR "cmd /C del /Q" to delete files.

In a portable Makefile i have to set that command conditionally,
depending on the OS, which leads to the problem to determine
the underlying OS.  Is there a bullet-proof way to determine
it?  Environment variables could be set not properly or also
not at all set.  Also, i can't set it for every command.


Would it be an improvement to add some very often used
commands like $(unlink LIST) and $(filecopy LIST) to
function.c?

Is there a reason why this has not been done yet?  Maybe
there are some strong arguments against that?


Best regards,
Torsten.
