This is not autoconf-related, but automake, as Makefile *generation* is done
by automake; autoconf only substitues patterns in Makefile.in to get
Makefile.

The right place to look at is at the automake-supplied "depcomp" script:
just add an entry in the big "case" with the naem of the compiler and th
eway to generate dependencies. If th ecompiler can do that as a side-effect
of compiling the source file, it must be placed *before* the commented-out
"nosideeffect" case tag, and after if this needs a separate run through the
compiler.

PS: modifying depcomp is enough; automake will automagically discover the
new way to generate dependencies from your change in depcomp... You do not
even need to have automake installed on your system: the depcomp script is
delivered with packages and the configure script is able to automatically
use it (if the package was automake'd of course).
