Sorry. I'm not sure I understand. You snipped all my code. Did it not
work for you? I use it on a daily basis.

I do use makefiles. It's in the code I gave to you. If the makefile is
not there then it uses gcc directly which is what you said you
wanted. Here it is again:

Yes, I do know that. But why would I do that when I can automate it as
above depending on whether there is a Makefile or not?

I'm not sure I understand. I have makefiles for most of my projects. If
I don't have one it builds a compile and link command based on the c
file name which is what you requested.
Sorry I can't be more help. Did you try my code?
