Unfortunately, I don't think there is a standard switch.  For example, I
think some compilers use -M.  I'll have to make some inquiries about what we
should do.  There is a discussion of the complexities of F90 Makefiles in
comp.lang.fortran, e.g.,

(If this URL doesn't work, I did a search on autoconf in comp.lang.fortran)

There are two problems; different compilers use (a) different switches and
(b) different conventions for module names (a.mod, a.MOD, ...).

Perhaps we should remove Nxdump from the list of targets.  It's not so
useful now that we have decent NXtoXML conversions.  The Nxtest is more
problematic though.

Fink have now updated their HDF5 distribution to 1.6.  Indeed, the
compilation now works for both HDF's, which is good news.  However, it means
that the API is not backwardly compatible for those with pre-1.6
distributions.

Uwe, can this be fixed to work for both 1.4 and 1.6?  I guess we can
probably tell everyone to update their version of HDF, but I would prefer
not to.

Thanks again, Freddie.  We're nearly there with autoconf.  Anyone want to
tackle RPM's?

Best regards
Ray
