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