This is rather strange. It's not clear to me how it could have
happened that you can find autoheader, but none of the other auto*
tools.

I rather strongly suspect that the reason for this failure is that MS'
compiler doesn't comply with Unix-ish standards regarding options for
a C compiler --- "why should we?" is MS' typical point of view in
these matters.  

In particular, I don't think it ever interpreted option "-ofoo.exe" to
mean "call the generated .exe file foo.exe".  It expects
"/out:foo.exe" instead.  And that's just the first in a long series of
similar discrepancies.

I guess you will have to provide a wrapper program (Batch file, bash
script, or whatever), that reads a Unix-ish "cc" command line, and
re-writes its arguments into the syntax expected by 'cl'.  For further
simplicity, you might just as well call that script 'cc'.
