[svn-r10657] Purpose:
Configuration feature

Description:
Fortran integer types (not reals) are now automatically detected at
build-time.

Solution:
Two helper programs are used, one to detect what types the Fortran compiler
has access to, and one to generate header files for C and Fortran matching
up types.

Platforms tested:
mir, copper, modi4, pommier (last week)

Misc. update:
MANIFEST updated, H5f90fortran_types.f90 removed from configure.in, since
it is not longer generated by configure.
