Makefile separator

[Massimo Giudici]

Hi 

I'm a problem with the Makefile 3.75. That is ,if I've to compile more than
one file and I put the list of file on Makefile with separator "/" the make
return as message error "... has modification time in the furure ...". I
think the problem is the separator ,because if I try to compile only one
file it function.
Could you help me ?

Thanks
