Unfortunately, autoscan deals primarily with C, not Fortran.  So I'm not
entirely surprised that it isn't turning up much.  But running autoscan
tends to be a once-only process done at the initial autoconfiscation
time, and not something done regularly (that explains why it doesn't
work as well); and since it is not a prerequisite to writing a working
autoconf.ac and using autoconf, it shouldn't hurt if you skip that step
as useless in your situation.

Quoting style - we recommend:

AC_INIT([myconfig], [version-0.1])

Oops - you called AC_INIT twice.  It should only be called once (and
hmm, maybe we should improve AC_INIT to detect and diagnose duplicate
invocation in a nicer manner than just complaining about unbalanced
diversions).

Do you really want to test for AC_PROG_F77 if you are compiling f90
sources, or did you mean AC_PROG_FC([], [Fortran 90])

Also, have you read the automake tutorial?
http://www.gnu.org/software/automake/manual/automake.html#Autotools-Introduction

It sounds like you want to use both autoconf and automake together, if
you are worried about tracking which .f90 files are built into your package.
