I removed the autoconf list from the followups. Dependency tracking
doesn't involve autoconf.

Could you submit a bug report to the automake Gnats? Mark it
"critical/high". We need to fix this before the next release.
There should be a link to Gnats from http://sourceware.cygnus.com/automake/
Thanks.

I think the goal here should be to have the Fortran compiler generate
the include information -- it can list both the files included via
#include and those included via INCLUDE. This way you get complete
dependency tracking as a side effect of compilation.
Writing a patch to g77 to do this shouldn't be all that hard.

Yes.

When possible, fix the compilers. When not possible, maybe living
with less than perfect information is the only approach.

This should also be solvable if the compiler is intelligent.
