Problem with modules and compiler versions

Hello,

I have encountered a problem with the intermediate module files
that result from the use of modules:

I installed a minor upgrade of the CVF compiler and this complained
that the .mod files for my program (compiled with an older version *)

The new compiler (version 6.6C to be precise) complains that these
intermediate files are from an incompatible compiler release.

This is a rather unfortunate circumstance: this means that we need to
recompile our libraries each time the compiler changes sufficiently.
Is this a common occurrence? In former days, compiled libraries used
to remain useable almost as long as the compiler vendor did not
change...

I have not been confronted with this problem before and as I just love
modules, I am unhappily surprised (and with me my colleagues, I may
add).

Regards,

Arjen

* I do not know how old, as the original compiler that I used for
  that was on a PC that has been replaced. SO it is neigh to impossible
  to check it.
