Given the URL you posted, I'm inclined to say this should
be closed with WONTFIX.  It is a clear violation of the
standard:

Note 2.2 in F2003 states:
   This standard places no ordering requirement on the program units
   that constitute a program, butmbecause the public portions of a module
   are required to be available by the time a module reference (11.2.1)
   is processed, a processor may require a particular order of processing
   of the program units.

In 11.2.1, one finds

   The USE statement specifies use association.  A USE statement is a
   module reference to the module it specifies.  At the time a USE
   statement is processed, the public portions of the specified module
   shall be available.

When the USE AFTER is processed, the public is not available. period.

Is really that difficult to re-order the code?  In particular, how
many other compiler accept your code?
