Agreed!
I've just started a fortran 90 project and I mean to have the GNU build
system on it. There were two major problems I encountered:
- Must make manual rules. I generated the rules with dependency tracking
using a 'makemake.pl' I found somewhere (I can link/paste it here if anyone
has trouble finding it on the internet) and made the needed adaptations for
it to work on a Makefile.am (seemingly it worked! hehe)
- Although all code files as .F90 (preprocessed fortran 90) and .h (header
files), autotools require me to determine the 'c' compiler on configure.ac
(AC_PROG_CC).
I found a discussion about a good soul who was willing to build such support
but, it seems excessive rules for the code to be accepted shoved him off the
game. Not sure tough.
I can say I will be an addictive tester of such a functionality shall it
ever come up. It is not something too complex as a 251-lines-big file is
enough to create the dependency rules.
Another thing I tried as an attempt for that dependency tracking was to add
on configure.ac the plugin macros AX_F90_MODULE_FLAG and
AX_F90_MODULE_EXTENSION. They did nothing as far as I could see. As it
looked easier to make it with manual rules, I ended up this way. Maybe I
missed anything but, if there is no support for f77, I assumed it were not
working on f90 as well.

Your correction of Jeff's solution made me realize that my "version 3"
solution is wrong. It expresses a foo-->bar.h dependency instead of
foo.o-->bar.h dependency. Your approach is what I was looking for.
Unfortunately this solution gets even uglier looking if foo has any
per-target flags such as "foo_FFLAGS=-I.".
Agreed. Most of my fortran includes are in different directories, making
the manual Makefile rules lengthy / ugly / complicated.
I.e., perfect for generation in .deps/. :-)
