! { dg-do compile }
! This tests the patch for PR34975, in which 'n', 'ipol', and 'i' would be
! determined to have 'no IMPLICIT type'.  It turned out to be fiendishly
! difficult to write a testcase for this PR because even the smallest changes
! would make the bug disappear.  This is the testcase provided in the PR, except
! that all the modules are put in 'use_only_3.inc' in the same order as the
! makefile.  Even this has an effect; only 'n' is now determined to be
! improperly typed.  All this is due to the richness of the symtree and the
! way in which the renaming inserted new symtree entries.  Unless somenody can
! come up with a reduced version, this relatively large file will have to be added
! to the testsuite.  Fortunately, it only has to be comiled once:)
